I had a coin like this. Strong growths made it almost indeterminate, but I was lucky enough to see what kind of coin it was and what year it was. This is a copper coin of the 18th century, at the end of the video you will see everything. I checked the catalog, it turned out to be an ordinary copper, they are very often found by search engines. Accordingly, such a coin, even in good condition, is not worth much, not to mention my safety. It's a pity to throw it away, so I decided to do an electrolysis cleaning and keep it as a souvenir. Cleaning by electrolysis is good because you can quickly clear the field of the coin. And if you have an adjustable power supply, you can control this process. But again, I recommend trying on ordinary coins first. For rare and valuable antique copper coins, this method will not work, remove all the patina and spoil the coin! It is better to give it to professionals for restoration.
