Another few things about stapled coin flips, are that the staples can rust over time, plus the seal is not airtight (unlike the adhesive types), so will allow harmful elements in the air to react with the coins. I've never used stapled coin flips.

[@bombfog1]

Wow, I just keep all of my Denarii, Aurei, Obols, etc. loose and in a coin purse, which stays in my everyday carry backpack. I like to share them with people daily. I love the look on people’s faces as they handle 2000+ year old artifacts for the first time. They are excellent conversation pieces.

[@ClassicalNumismatics]

Everyone should have a couple of carry piece! These are great conversation starters

[@TheTaurus454]

Sir, Could you please make a video on how to read the reference annotation that come with coins? For example, CII, RMI, 231, 427 is a made up example for your reference. 😊

[@homerj806]

Way back in the 90s when I started collecting, there was not much info on PVC and long term storage; mylar flips didn't exist yet. So when I bought the plastic flips I did ask about how safe they are with my coins and the supply dealer said they were fine. Fast forward 25 years and I started picking up coin collecting again and pulled out the old albums and noticed green on the coins especially on the silver. I spent more than a week, cleaning up as much of the PVC and getting high on the acetone I used as the cleaner.

[@jaha9329]

Big umpf. Instead of acetone, I would recommend a 2:1 distilled water/vinegar solution. If damage is not too severe, simply dipping a coin for a few seconds works wonders, and getting high is not an issue then. The only important part is to clean the coin afterward in distilled water to remove any vinegar traces (tried this on modern coins, but I'm not sure how well would ancient coins respond to such treatment).

[@chryoung-db2iw]

@@jaha9329 I heard olive oil works not sure if it’s true

[@homerj806]

@@jaha9329 Different techniques for different situations. I have used them all and I found it depends on the coin. I even used the very "dangerous" electrolysis method. I had one large roman that was in baked mud. I tried everything but nothing could penetrate the outer layer of the mud. It was like trying to scratch a brick and I didn't have power tools. So I used electrolysis and to my surprise it was an uncirculated Julian II when the mud casing fell off. I double checked the mud and there was no patina. The baked mud preserved the coin. It has since tarnished like all copper does.

[@Gilbertoooooooo]

The vinegar will make ancient cooper coins go bright and destroy the patina, acetone is safer I think

[@OneMinuteKnifeReview]

Good information! Having grown up with a collector as a father, I was brought up knowing most of this fortunately for my collection.

[@ClassicalNumismatics]

Thats nice! What did your dad collect?

[@ragnaroni]

For my Roman coins I use one of those red velvet trays with a card beneath the coin for information. For my modern coins (modern being a relative term here haha) I use these like drill bit boxes, they're (afaik) supposed to not be causing issues since well drill bits are metal too but they are bulky...

[@Ant2242]

If one uses staple flips it's very important to flatten them to help avoid accidents in transportation and storage. When removing coins from these flips its best to break the window to avoid any unnecessary accidents with the steel staples. Also they are considered disposable storage. I have seen many good coins get scratched when people try to reuse them. People need to also remember to not just jam the boxes they keep their flips together. It's best to leave some room so that the carded coins don't have too much friction together. The Mylar windows are very thin.

[@ClassicalNumismatics]

Thats true, When opening a flip, I veeery gently open the plastic window with some tipless scissors. Your advice on adding a bit of space between flips is EXCELLENT.

[@Ant2242]

@@ClassicalNumismatics I've had success in opening them with toothpicks, point of a ballpoint pens, and sometimes a bend will snap those thin plastic windows. Also I forgot to mention but there are staplers that have the option, if not the purpose of making the staples flat.

[@trilobiteterror8015]

I use Mylar flips (mostly Saflips). They're a bit expensive, but well worth it in my opinion.

[@johnnail532]

Great information about storing coins- thanks. The coins you showed are also beautiful- I wish I saw ancients like that more in my local coin shops

[@colbystearns5066]

I use saflips for storing my coins/info cards and place them in a large album (also having no PVC) that’s big enough to hold them together. They’re organized in different categories, chronologically for Roman emperors and other themes like women, foreign rivals, usurpers, etc.

[@ClassicalNumismatics]

Great! Very neat and organized!

[@TheWinstonDouble]

A fun fact I recently learned is that PVC isn't the issue... it's the plasticizer they put in the PVC that causes the problems. The plasticizer makes the PVC soft and pliable. Unplasticized PVC, or U/PVC that says "archival quality" won't give you the negative effects. It is a more rigid/hard plastic like mylar. Despite this, I still reccomend mylar saflips if you like this storage method. My preferred storage is the cardboard 2×2s, and then I decorate them with calligraphy. The calligraphy makes me go through a lot more than 1 set of pens. A $5 archival art pen might last 10 or 15 flips, but it's a great way to enjoy my collection.

[@chryoung-db2iw]

That’s what I heard it’s not the pvc itself but the plasticisers that cause it but some say it’s pvc itself tat does it’s all very confusing espily terms like acid free pvc

[@nazarnovitsky9868]

Thank You very much for this new video !!! 😊

[@ClassicalNumismatics]

You are welcome! Hope I was able to teach you something new today.

[@ulexite-tv]

I was raised in the era of white chipbosrd 2 by 2s and still like them best. Never open them by undoing the staples, just break the plastic with your thumbnail or a little pen knife. I think of them as home-made slabs, LOL!

[@ClassicalNumismatics]

Lol, that a nice way of looking at cardboard flips!

[@marianmoses9604]

On stapled 2x2 I simply use a pair of scissors to cut away parts of the 2x2 containing intact staples. Then I safely remove the freed coin with no risk of it getting scratched by the pried open end of a staple.

[@ordinary-ride-1595]

I think in your upcoming coin cabinet video that you make, you can include the best way to store coins using my favorite custom circular archival hollow tags. :)

[@briank7936]

Great topic. I was wondering about ink for use on flips and cards. I use both stapled 2x2 and archival safe paper envelopes. Envelopes are for coin trays so the coins slide around less. 2x2 are for boxes or a 3 ring binder with 2x2 slots to make looking at coins easier. I never remove staples from a 2x2. I take the coin out through the plastic and throw the old flip away. Less of a chance of scratching the coin. I would use the adhesive ones but I already have a ton of the other 2x2s.

[@ClassicalNumismatics]

Very smart point on the paper protecting the coin from any friction with the fabric on the trays!

[@officeguy3]

I use the archival envelopes for my ancients as I like to handle them. Recently a friend wanted me to look at his coin collection before he sold it. Unfortunately he had stored many of the coins in plastic flips containing PVC ruining most of the collection. It was a green sticky mess.

[@ClassicalNumismatics]

Oh nooo! 😧 Acetone might help, but the damage might be too great for only that to fix it.

[@Ant2242]

On modern issues 100% pure acetone and then distilled water followed by a very light pat drying on fresh microfiber cloth works. Be careful not to apply friction.

[@iamtiberius]

I would recommend bleach free paper. I used pvc free BWC flips and they left a greenish film on most of my silver coins over the course of 5-10 years.

All my ancients are in soft flips or graded. 2x2s I save for regular modern issues. Main reason is I usually get them in soft flips to start with.. so I just leave them as is.

[@marianmoses9604]

The soft flips are the ones with PVC plasticizers. If you leave your coins in them they will eventually be ruined by reacting with the PVC. 😬😯 Did you not pay attention to what this nice man just tried to teach you? Seriously. 🤨

[@Francoaferrero]

Do You know if pvc has to be in direct contact to damage the coin? I use pvc free flips but store them in album pages that easily bend (im not sure they have pvc)

[@ClassicalNumismatics]

Thats fine. A mylar flip can sit inside a pvc plastic sleeve without any risk to the coin

I bought some modern Jewish silver coins stored in paper flips with plastic windows. Some of them reacted with the plastic and were covered in green gunk so I would disagree with the statement that all of them are 100% safe for coins. I store the rest of my coins in acid-free paper envelopes.

[@ClassicalNumismatics]

Well, that plastic had PVC in it then. Thats why I mentioned its important to double check if the little plastic window is PVC-free. You did good in storing them in acid-free envelopes. Thats a guaranteed way of keeping them safe.

[@jaha9329]

@@ClassicalNumismatics Those Jewish coins are actually a funny story because I bought them specifically because they were afflicted by PVC. I had this partisan 5 złoty coin, precious for our people. Unfortunately, some moron stored it improperly and it was covered by green gunk in specific spots, but I was too afraid to try to clean it without proper experience. Cleaning those Israeli coins gave me some experience so I knew what can damage silver and what cannot. If anyone has a modern silver coin with PVC disease, this gunk is easily removable with distilled water/vinegar solution in 2:1 proportions. Just make sure to try it on some cheaper coins first!

Any little small transparent plastic bag, or small plastic container will do, for the time until proper flips get delivered to you.

Okay, that's great because I personally find capsules the best way of storing coins, but if it's bad, I would stop . In my opinion, it's always better to ask someone who knows what they are talking about than to just do something that might damage artefacts .
