I found this, surprisingly, in a roll of nickels. It was able to just fit in between 2 of them. I cant find anything about it online but im thinking maybe its the copper coating off of the back of a 1981 canadian penny. That would explain why the rim is cut off, and there is only a feint design on the front of it. leave your opinions down below on what you think it is and what you would value it at.
I highly doubt that. there is no discoloration or wear anywhere on it. possible its post mint damage, but definitely not being in an acidic environment.
Is the size of the coin correct? You say it "just" fit into a roll of nickels, so my best guess would be that it was hammered down to nearly the dimension of a nickel.
what i mean by what i said is it fits in the lower part of the design on the nickel. its small and thin enough to fit between 2 nickels with the rims of the nickels still touching. It's the same size as a normal canadian penny, but with the rim cut off
That's because it is the same metal all the way through the coin. Doubt my answer all you want. It's still the correct answer.
I've encountered these kinds of coins before. Here's a question I have about them. If the entire coin is solid bronze or copper, for example, why doesn't the acid dissolve the entire coin? Why does it make them paper thin with the "core" remaining intact?
I found one in an alley, It was in very greasy gasoline like soil. I havnt seen it in a while but it was about twice as thick as the OP's, believe it was a 46'.
It may/could have been glued to the end of a stick/rod and then suspended into an acid/caustic solution. Some of the experiments done in schools are about electrolysis.
I haven't done it in a long time so I forgot about it but it makes sense that this coin is a product of electrolysis. Electrolysis will eventually eat down a coin like this in ways that differ from an acid treatment.
I have nothing to contribute but I thought that the second photo of the edges was just a cut on your finger until I looked at it a third time.
