I Made a Working Lego Coin Sorter

I built a coin sorter with only Lego! It can take any coins and sort them in order by price. I needed something to sort my money, and now I got it! How it organizes the coins is also a very interesting process...

I fix coin sorters for large grocery stores. The dirtiness of coins cause issues even in the best sorters. The best coin sorter i have worked on uses a rotating near virticle rubber wheel to get the coins on their side, then it will sort by height by knocking the tallest off the track first then getting smaller. Hard to explain in a KZbin comment. Great first attempt

[@robintay1449]

Thanks for taking the time to explain.

[@pinobluevogel6458]

It's comforting to hear from a professional, that it is actually quite a hard job to do. This makes this early prototype sorter from lego parts even better.

[@CJ-ht4rf]

The dirt slowly rubbing off of the coins was my first thought too. You can tell at the beginning they definitely slid much faster and then it got progressively slower the more times he tried it

[@thomashverring9484]

I've been working with huge coin sorters, I mean industrial size, and they still get clogged up by dirt. Cleaning them everyday was nasty.

[@weirdestbudday5353]

This comment should be pinned. It's great and useful info to help us all understand better

[@ZacharyC]

For the problem with the coins getting stuck maybe take away the turn since it's losing a lot of it's momentum while going into that turn. And maybe add some sort of power function system that is able to vibrate the actual sorter so that even if the coins do get stuck they'll eventually fall into the desired slots. As for the coin being on top of each other maybe you could have some sort of system that will allow only the thickness of one coin to go into it although this could pose a threat to the machine being constantly jammed. I hope you develop this project further as I don't see too many coin sorting machines out of lego.

[@h1ghdipp3r32]

or just make the flat pieces on the sorter thinner so that there is less surface area on the coin and it will slide better

[@jaredwonnacott9732]

The turn makes sure that all the coins are sliding against the far railing, because otherwise coins could be a little off the rail and miss their slot.

[@brlinrainf]

My idea is to put water on the lego so it helps the coin move

Right, and to follow up on this, had US kept using silver, the nickel and penny would have been really small. US was forced to use different metal for nickel and penny so they are bigger than a dime

[@GoldenMysticat._]

Bruh sometimes it's a c or a x

[@patrickdix772]

Since I've always found coin materials interesting, some more info. The US silver coins used to be a silver copper alloy (for durability). Modern silver US coins (except nickels) are now a copper core with a copper nickel alloy cladding (changed since the value of silver increased in the 60s). The modern "gold" dollar coins actually have no gold in them. Older gold coins were a gold copper alloy (copper for durability again), and silver dollar coins were made for a long time too. The modern "gold coins are a copper core clad in manganese brass (a copper and manganese alloy). Nickels were originally called half dimes, and were established as "nickels" in 1866 being made primarily of nickel, and modern versions have a higher nickel percentage than other "silver" coins. Pennies varied a lot over time, starting as 100% copper, and varying greatly as metal prices and demand shifted, including a steel penny used in WW2, now almost entirely zinc with a thin copper coating.

If you look at the Japanese ticket machines or tills, you may find some inspiration: you can throw money inside and the machine will perfectly count the money and also identifies the ticket you are using in-between the coins (for machines in buses, where you throw the money and ticket all together before exiting the bus, to demonstrate you paid the fare). Anyway, it's basically a funnel, but designed in a way that the weight will not jam everything.

If you say the half-dollars are huge, image the ike dollar (eisenhower dollars). They were the dollar coins before the sacagawea dollars and the small presidential ones. They were twice the size of half-dollars (in weight). Also, dimes are the smallest because before, they were worth their weight in silver. So the weight of the coin was the value. However, for pennies and nickels the metal was not the same.

[@Nominal-Lettuce]

​@@ME-kd1ko You are right, I will fix it.

[@00linered]

The coins are stacking because they climb over the ones that are stuck. Keep them from getting stuck. A small motor with a counter-balanced weight on the end can be used for a vibrator. Tilt the assembly slightly vertical more yes, but with the angle you need to get them to roll by themselves you will not have as much help from gravity, they will most likely have too much speed and roll right past the hole. As someone said, put a funnel and take out the turn. I would add the vibrator to the finish line of the assembly and a tapered gate with fingers at the bridge from the funnel, preferably with flexible material to help reduce jamming.

[@jimmypockrus7725]

Coin sizes were set when it took $0.10 of silver, pennies were made of copper and the size was the amount of copper to equal $0.01. The Nickle was how much nickle was worth $0.05. And so on. Now none of the coins are made of solid whatever substance, and it costs far more to make a penny than what it is worth.

[@InventorZahran]

I thought the whole point of sandwich coins was to reduce the cost of minting...

One of my first custom LEGO builds (i.e. not following instructions included in a set) was a coin sorter that could differentiate between 2€, 1€ and 20cent coins. It worked flawlessly and is still standing as part of the wall of a little LEGO house in the attic in pur house back in Germany.

Oh man this is the kind of project I like doing with patrons at my library (mostly kids but I wish more adults would get into it too - my programs are designed for certain age ranges but all of them are open to all ages). Yeah I've decided. We're gonna do this project for one of our lego clubs.

[@Me_the_idiot69]

ill do my best to explain why the nickel is bigger then the dime. in the early days of the usa, the coins were worth the metal content, so a dime was made of 10 cents in silver, etc. and we had a half dime, whih was smaller, but worth 5 cents, and in 1866, silver was going up in value, so we moved over to making nickels, which were worth 5c in nickel, im glad this guy isnt sorting the 3 cent pieces and the 2 cent piece. that would make it a lot harder. nice sorter, gets a sub from me

For an autofeeder if you have a box with a spinning part in the bottom, like a stirring to push them onto the slide part. Maybe a slightly angled ledge above the pusher so a few fall down there at a time so they weight doesn't just jam the whole thing.

[@brickstudiosYT]

The only issue is that two dimes could fit in the same slot vertically as a quarter or anything larger. But other than that it might work. Thanks for the idea!

[@Canine_Medal2316]

Id suggest putting a layer of 6 by whatever plates over the top instead of lining it with 1 by whatever smooth plates. This way, only so many coins can go through. Also having a side bar attached to it to store the coins on their sides and moving the slot to the side should ensure that only one coin goes through almost every time.

[@Shawn47]

The sizes are exactly proportionate from when they were silver. A silver quarter weighs 2.5 times more than a silver dime. A silver half dollar weighs 2 times more than a silver quarter and 5 times more than a silver dime. A silver dollar weighs twice as much as a silver half dollar, four times as much as a quarter, and ten times as much as a silver dime. Pennies and nickels weren't silver, so their size was not dictated by their weight.

[@djk6297]

During WWII copper was an essential war material. As a result, nickels had silver in them for some years. In 1943 cents were zinc-coated steel, making them much lighter.

[@jeffmarner3106]

I came here before you finished and yes I agree, you should have it so they roll more vertical instead of sliding.

[@zachsmith2349]

Dimes and dollar coins are smaller than coins that have a lesser value because of a desire to maintain a scaling property between dimes, quarters, and half-dollars. Each of those 3 coins contains the same blend of metallic alloys (the other coins are different blends.) Further, each of these three coin's masses scale exactly with their values. I.e. a half-dollar has twice the mass of a quarter and a quarter has 2.5x the mass of a dime. That way, any given weight of dimes, quarters, and half-dollars has a set value, regardless of the mix of the coins. If you had some amount of those three coins, any equal value substitution corresponds to an equal weight substitution. You can take a half-dollar from your pile of coins and replace it with five dimes and the value and weight of the pile remain the same.

[@senormudbone4247]

You should definitely build a cool and uniform outer-casing for the internal machine (everything you’ve already built) housed within a cool Lego box. You can even include snot brick character elements to enhance the look. Another idea would be to implement a way to add empty coin rolls to be filled by your Lego sorter just like real ones do. Overall INCREDIBLE build. So amazed and impressed!!!! Keep up the incredible work!!!

[@Kasperbjerby]

Make it drop into a bigger container so that there is space for more coins, make the whole system less compact and make more room for the slides that move them around, put the whole thing on a shaking platform to force them to glide even when they are dirty, and it should all work 🤗 Then add a feeder 😉

[@user-nj1ye9sj3e]

I’d make a ramp leading up to the coin inserter which would also add momentum but still sort them on by one.

Maybe a light spray with silicone oil and polishing off with a clean, lint-free cloth might help getting the coins down the ramp. Also, a small battery-powered vibration motor connected to the ramp might be helpful as well. Just some thoughts from somebody who tried something similar for Deutschmarks... 😄

[@InventorZahran]

A bartender in the U.S. once accidentally gave me a Deutschmark with my change instead of a quarter. I added it to my international coin collection!

[@targetdreamer257]

Maybe use Lego motors to add vibration to a coin hopper and make the exit only one coin thick?

[@W0lley24]

To help with coins getting stuck down the ramp, try rubbing paraffin wax, or a candle, on the ramp then polish it off with a clean cloth. Good job on the sorter!

[@Lampe2020]

If you want to input a bunch of coins at once you should make a slanted spread plate, where you dump a few coins on and spread them out by swiping the hill of coins around, when they're flat they can slide into a slit at the lowest corner to go into the sorter one at a time. And I'd recommend you make it a rolling sorter, because I built one some years ago and it sorts the coins while they roll down a ~45° slope and lean against the wall of the completely-vertical, 1-stud-wide channel. I got them all leaned on the same wall by letting them slide down a short ramp into the sorting channel.

[@michaelburens499]

One thing to try would be to have a belt system that rests on top of the track you have made, to push/pull coins to their slots, and it would reduce the chance of coins getting stacked on top of eachother, as for the feeding system, it could also work with like a funnel that flattened out, with part of a belt pulling coins in one at a time

[@Mr2010forgeben]

My pride and joy as a kid was a candy machine that wouldn't work without the right coin.

[@sysghost]

This reminds me of my old LEGO projects when I had a huge box full of LEGO. Did very similar things. I vaguely remember doing some coin sorter too.

[@onefourfiveninef3itssteven774]

make is so that there is a hole in the bottom of a tube/cylinder and the coins drop onto a platform. There is a sliding thing on the platform that pushes the coins into a seperate chute where it falls into the sorting mechanism. This is the simplest way I can think of, and it allows the coins to enter the sorting mechanism one by one

[@igognito1]

The easiest solutions i could think for the three problems you have are: A lego pouring cone to allow multiple intake but exit of one coin at a time. Allow the cone to rotate so if something is stuck you rotate it and it resumes 2) increase the inclination or add the technic mini wheel instead of just tiles. That might make it a bit thicker. 3) to improve performance pass the coins two times from the sorter instead of once that will help if coins are one over the other

[@wolfetteplays8894]

Reminds me of this book I used to have when I was younger, where it showed you how to make 50 lego machines. It was awesome.

[@BrianJoslyn]

You should definitely, 'perfect,' this. But, correctly. You made this more complex than it needs to be. As a child, I actually had a bank with the drop slots, in the correct order ... dimes, pennies, nickles, quarters - I don't recall if it had half dollars but I do know it didn't have dollar coins. It did have a separate dollar bill slot. It also held enough of each coin to fill coin wrappers. Coins could be dirty and no need for an automatic sorter to dump multiple coins at once. It's not a machine to count how much money a vending machine collected.

[@alexsouthpb55]

For batch sorting, I would have a gently slopped shelf in the shape of a Y which funnels coins to drop off the edge vertically onto a ramp so they then roll down the ramp towards the sorting holes. There would need to be some way to vibrate the shelf so that the coins slowly trickle forward.

[@chadm5629]

I built one about a decade ago. My needed extra engineering because I didnt have technic or snot pieces. I cant dump a bunch in, they have to be fed one at a time, but it never jams, never gets stuck, and never sends a coin in the wrong chute. If you'd like to see how i did that let me know. I later made one out of wood based on the same concept that I actually use. The lego one sits in a cabinet.

[@ScratchedSpeed]

[@JaNeLLeJuSTiNe]

I would put a bar across the top to make sure coins dont stack on top of each other when sorting, (like the height of 1 coin) that's how some coins were able to bypass thier respective slots.

[@NotKnafo]

thats cool! maybe change the tubes to drop into containers so coins wont jam

[@aliadel1475]

Right now you can fix this using gravity you can make the coins sideways it a really good idea, you want to make most of them drop down not in an angle, SO you can make 1 of the coin go around another instead of 2 switching with another this makes it more consistent, and reduce jamming problem. If you can make a thing more simple, do it. complexity is harder to do and comes with more problem.

[@videocarrot3497]

Idea: Extend on the slots where the money goes by attaching containers for them to drop in, because you can’t fit much in how it is. You would obviously need to secure it aswell.

[@jeroen3673]

A working coin lego sorter would be much more impressive 😅

[@Lost_n_Found_1]

Track should be oriented vertically, with a slight slant backwards, to guide the coins into their correct chute. That's how older vending machines operated to deal with dirty and corroded coins.

[@accessyourinnerlight971]

The reason the dime is smaller than the penny and nickel is because the dime used to be made of coin silver and it was once 1/10th of an ounce of coin silver (an ounce being a dollar of silver). Pennies were once entirely made of copper and were valued at a cent and a little bit over (the extra amount of the penny value was supposed to help pay off the national debt). Nickels are (perhaps unsurprisingly) mainly made of nickel and zinc. The quarter was also intended as a silver coin and once had a weight of 0.22 ounces. (being slightly less than a quarter ounce of coin silver). The Kennedy half dollar was originally a silver coin having a little bit over a third of an ounce of coin silver. Of course, today's coins do not have anywhere near the same intrinsic value in metal as most coins are now entirely alloys of nickel, copper, and zinc.

[@ERYN__]

Cool. I had a coin sorter that sorted them into cylinders that were the same size as coin roll papers. I don't really interact with physical money much anymore.

[@khadijeazimi1788]

The video had everything except the thumnail

[@janthran]

the reason it started having issues was probably less about the coins being dirty and more about the overall weight of the system stopping it from shaking and letting the coins move more freely . you could test again with it emptied out and see if it starts jamming around the same volume

[@casekocsk]

In some of coin sorter, the machine vibrates to avoid stuck coins. It's the same as you slam the desk with your hand.

[@gavinsl4188]

To help the problem with the stuck coins you can put a spinning fan kind to act like a spinning door to push the coins and to make the process smoother

[@prosaldozwiler4257]

The coins could be guided past the traps on a conveyor belt and a scanner pushes the coin into the correct opening using flaps.

[@fionaperry5718]

[@brlinrainf]

How about putting a lot of wheels on top to slide the coins and it uses springs too to get a good grip on the coins Put a slope after each hole so the coins has less chance of going over the hole

[@anshsgh6092]

[@TheMulToyVerse]

Maybe have a technic style conveyor belt that you pour your coins onto (steady pace) then as it runs you keep adding to the belt Not sure what could be done to consistently account for non-clean coins… if you make the angle sharper then clean coins might have too much momentum and “clear the jump” as it were and if you try and make a ramp style system where they drop down from a vertical state then they might clip’n’skip to the next chamber Either way you’d want to make the unit taller to allow more coins to collect in each chamber, but also maybe hinge clear window pieces to keep the coins from falling out the bottom, as well as a way to access the stacks better for when you want to coin-roll your change Good v1 though… but I kinda wish that the thumbnail wasn’t totally misleading in terms of the finished prototype

[@tjtobin86]

You could add a very small vibration technique (like a game controller offset spinning weight) to gently shake the machine and keep the coins moving the whole time.

[@notsameeverywhere4184]

I would try to make it work with "wings" instead of holes. (1st wing flips biggest coing out of track.. etc...) That way you can make the track more vertical and coins can roll more than slide. Maybe that helps with a friction.

[@maxojafaridze2098]

u can make something like lego funnel and u can built it on top of that too where u drop the coin

[@orangeapples]

Perhaps use some technic pieces to act as an agitator so the ramp is moving and gravity can move the coins. Also, i think coin sorters have the coins on their edge so they can roll regardless of how dirty the coins are.

[@ThomasMcGuire-ge3kn]

I got curious about this video because I made a coin sorter of my own awhile ago, and to this day I've been upgrading it a lot. It's now the size of a basketball, but as a cube, and the lower half is all for storage (so I don't have to worry about too many coins like you did with the pennies). The upper half is split into to other parts, one that is drawers to actually hold dollar bills from $1 to $100, and the other part is what actually sorts the coins. The sorting system is also vertical, like what you were talking about at the end of this video, and I have no issues with the coins getting stuck or not moving all together, but that also has to do with the angle that the sorting part is at. I know I had to tinker with how the coins are sorted, mainly the penny and dime because of their close size, so I had to actually improvise and make some kinda weird formation that catches pennies to keep them going but the dimes end up falling down. In the storage, I only have pennies, nickels, dimes, and quarters (half and full dollar coins didn't seem worth it because I, like most people, don't have many of those), and each coin has about a quarter of the 32x32 (I think that's the size anyway) baseplate that the entire structure is built upon. I've also built a few other compartments, such as one to hold a brick separator, another holds two rods (one's hard and the other's flimsy, and they're for unclogging anything), and the newest one that I added on actually holds my wallet (I thought it was a fitting addition since this whole machine now has all of my money that I have that's not in my bank account). Since I've done so many tiny tweaks to the sorting of the machine, the rods and the brick separator hardly ever get used anymore because my machine is so precise and I haven't had a clog in maybe a year now, if not longer. I've also placed the thing on another identical sized baseplate with a rotating piece and tiles surrounding it, so now the 20lbs machine can rotate on my desk (I had to also place a little grippy pad thing underneath the whole machine because else the base part couldn't actually rotate under it's own weight). I think you got a good start to a great coin sorter, and it was really cool to see another person's perspective on how one might build one of these.

[@007Strings007]

Something like this need to be a set it would sell, as a kid I remember thinking coin sorters were fascinating for some reason.

[@FireStarLP]

I think if you where to make this into a rotary system with a hopper on top you could avoid them from getting stuck mostlikley and build it into a nicer design where it would not use so many slanted pieces where the coins can get cought on jagged edges. And with that you can also use a LEGO motor to turn the coins.

[@fruitschnacks]

this was fun to watch. I'm glad you kept in the parts where the coins got stuck, shows not everything is perfect!

[@Debbiebabe69]

For comparison here is the sizes of UK coins, from most diddy to most big: 5p, 1p, 20p, £1, 10p, 2p, 50p, £2. Seems completely random. However, some coins have actually changed - the 5, 10, and 50p coins all got a redesign to make them diddier. The original versions went like this: 1p, 20p, £1, 5p, 2p, 10p, £2,, 50p The next thing to consider is metal. Although these coins were WELL after the age of making coins from valuable metals, the alloys used were chosen to imitate the old metals: Copper/brass - 1p, 2p. Fine Sterling Silver - 20p, 5p, 10p, 50p. Fine Bullion Gold - £1 Which leaves only the 20p, as this coin has its own history. When decimal coins were introduces in 1971, the denominations were 1/2p, 1p, 2p, 5p, 10p, 50p and pound. In 1982 however the 1/2p coin was discontinued as worthless, and replaced by the 20p coin. Before, all the other coins apart from the 50p were round, and the 50p was a heptagon. They decided for the new coin, as it was the 2nd most valuable 'silver' coin to the 50p, to make it a 'baby' 50p, so it was introduced as a heptagon like the 50p to distinguish it from the other round silver coins. Unlike most things between the US and UK, US current coins have a lot more history behind them and so I presume they will have similar reasons for the sizes.

[@orien2v2]

Maybe reverse the sorting so big ones will not bring the smaller coins with them as well. But yeah prone to jam so might need some power functions like a rotary arm to ensure constant clearance and flow.

[@yobgodababua1862]

Tilting the coins more on edge so that they roll more than slide is how most actual sorters keep from sticking. Also, dimes are (much) smaller than nickels because they were originally made from silver, whereas pennies and nickels were less expensive metals. Same deal with the (originally silver as well) half dollar and the (originally gold) dollar coin. In most cases we've kept the size (so as to not F up all the existing sorting machines) even when the reason for the size has become moot. Very nice build though. Bonus challenge: separate Canadian pennies from the US pennies...

[@pinobluevogel6458]

This is a pretty good attempt at a coin sorter, I think if you use gravity better and tilt the slopes further and more steeply, most of the issues of things getting stuck are solved. Also, making a curved path for things that have to go round, instead of slopes falling into slopes will lose less momentum, a sort of playground slide if you will, then getting the whole contraption higher up and having bigger containers will make sure there will be no clog of coins at the bottom. Lastly, having a more stable base shouldn't be too hard to accomplish, the whole thing looked pretty flimsy with the awkward angled legs. This was a fun experiment, thanks for posting it. It might be a fun idea, if you have the time and are willing to re-iterate on your design and make a second or third build after this, trying to fix the issues that you encountered. The whole idea of making such a project is improving while you do it and I think you did a great job at mentioning the current flaws. Also, as a general rule for a LEGO channel, having a nice looking color design is a huge plus. Just invest in the most common bricks in 2 or 3 colors, so you can at least build something that doesn't look haphazard. I'm not a huge brickowner myself, but for such a relative small build, it shouldn't be too hard to get something done in one or 2 base colors. Then again, don't take the criticism too harshly, this was a great idea and some very smart solutions for a functioning first design!

[@timmothycopeland4866]

Keep in mind, the steeper the slope the faster coins will go increasing the chance of the skipping over their respective destination.

This sorter should be looked at as “Mark I” and it should be worked on, or updated, in several stages until it’s near perfect, IMO.

No coin sorter (that I’ve seen for home use) is perfect. This looks like it works pretty decently. One change I would suggest is to make the entire thing taller. This will give you more room in the individual bays to hold more coins. Maybe you can tune it so that each bay holds exactly one roll of whatever the coin is?

Lego neeeeeds to make this a Lego set

[@jonathannerz1696]

The reason why dimes are so much smaller is because dimes used to be made of silver, which was much more valuable than the copper or nickel that pennies and nickels used to be made of.

[@theemmjay5130]

Huge props for using a Pick-a-Brick cup to hold the coins. Also, I wonder how many people who weren't already familiar with the concept of Studs Not On Top thought, "What's a snot brick?"

[@brickstudiosYT]

Yeah, I needed a container for them and I just grabbed a pick a brick cup. You're right though, I should probably make things like snot bricks a little more obvious to the non hard core Lego fans 😂

Most , if not all of your issues, would be solved if you had just made the slots from smallest to biggest and not from cheapest to priciest, but I guess you already know that. Even the stucking issue on top of the slider due to "dirtiness" would be solved because you could have tilted the slider more. But this version is cooler and you could demonstrate better building skills through this. I'm not that much into legos but super cool video and I might make an easier version for myself in the future, although I'm not sure if it would be possible for my country's currencies

3:53 made me chuckle 😂😊

Coin slide sorters do get dirty because of the dirty coins. So you have to clean the slide often. Sometimes putting baby powder on it will help for a while but really, it is hard to avoid it getting gunked up if you use it often.

[@jaredwonnacott9732]

What I'd do is create an initial drop that creates a little more speed, so that the coins have enough momentum to make it to their slot.

[@AriManPad8gi]

short conveyor system that vibrates so the coins all find their closest point to the Earth's centre of gravity. idea being that as they vibrate they slide off each other and are all even, plus a rigid brush on top to push any easily pushed ones. wouldn't need to be very strong. also more professional coin sorters wash the coins anyway, they have to by law since it touches people's hands and stuff. public hygiene laws, etc. try that out. it doesn't have to be long, oh, and think factorio belts :D

[@iavsj]

you should make the shoot one coin thick that makes sure they don't go above each other make the shoot more vertical as you said but make it so that they roll not slide make the coin base taller and make the queue sorter bigger so it won't get stuck!

[@series9999999]

Maybe apply some rubick’s lubricant on the slide section would help make the dirty coin’s slide without friction sir..maybe..n give closure on top every coin wells to prevent the coin’s flip out especially for the big coin issue..hope u find my idea useful,sir..brilliant video n invention u got there anyway sir..😇😇🎉🎉🙏🙏👏👏

[@-.-aaa]

So many people here offered there solutions! Great teamwork all around! 😀😃😄👏👏👏

[@marshmallowsandtrash]

This is so fun. I appreciate you showing what went right as well as when it goes wrong

[@timskeldon215]

its really cool but if you could maby get a custom clear bricks i feel like it would be cooler if you could see the coins going down

[@jenniferstine8567]

Have you ever been to a planetarium? They tend to have a black hole simulator you can run coins on. When it gets to the bottom the coins are moving flat. Coins also don't pile up on each other. If you find a way to use centrifugal force, you might be able to sort multiple coins at once. Try using clear pieces. It will make troubleshooting easier. Maybe make the chambers round so the coins land flat.

[@Frida3728]

Coins sliding over the Legos may be abrading the polished finish of the Legos, causing friction

[@RP-uv8qq]

Great first attempt. Would love to see one with a crazy mechanism like a pendulum dropping coins. I think if the top tray was also at a 45 degree angle so coins rolled and slip, you would get more consistent sorting. Also, why not build it high enough to let coins fall into paper rolls?

[@KidarWolf]

Have you considered using a motor to create vibration in the structure itself? Just an off-balance crank directly driven by the driveshaft should do the trick.

[@thanhlamnguyen2420]

You can. Add athin area of space to stopping the coin to sitting on top of each other

[@fainttomcat652]

How about mindstroms maybe make a color sensor and make a rack and pinion it takes it to it

[@danieldequit1403]

You should use a conveyor belt system just without the conveyor belt so the dirty coins won't get stuck problems by using the Lego wheel or something like that and from keeping the coins riding on top of each other you should leave a gap between the top and bottom of the coin

[@pindamonhangaba72]

I got the solution buddy Vibration Thath is the reason coin machines vibrate so much They make it way easier to slide

[@i_love.gotcha]

Idea make the fall slots wider and add a big ramp that should work

[@calzonemaniacsvideocorner0804]

Not that bad for a first attempt. I would make it a little larger and steeper to help facilitate the movement of coins.

[@JoranPrins]

Nice work! I also made one a while back, the 5C and the quarter were also very close in diameter haha

[@Justwayne88]

This is amazing love it,have you conaideredan off balance motor to cause vibration to allow coins to filter in amd prevent getting stuck
