The first step would be to take it to a local coin dealer. They can look at it and tell you if it’s fake or not, and give you a rough idea of the value.
I recall an incident with the new quarters at one of the Mints. A few years ago, an employee purposely messed up the dyes so new quarters with the new Washington image would be minted with the old eagle backs. Or, something like this. It was caught before the coins could go into circulation. I think the man did it out of revenge for not getting the raise he was expecting, IIRC.
Does any other Doper recall this? It may have been the Philadelphia Mint, IIRC. The year was 2000, I think.
I don’t recall that incident, but the striking of “rare” coins by Mint employees for personal gain is nothing new. The famous 1913 Liberty Head nickels are believed to have been struck for private enterprise, as an example.
A genuine two headed coin would be the product of two or more USMint employees taking their job in ther hands and conspiring to strike a few using mismatched dies deliberatly. The would quietly be escorted out of the mint, sans job and recourse.
Don’t mess in the mint, deliberate mistrikes or trying smuggle them out Gets You In The End!
Pseudo two headed coins are relatively easy to make as mentioned above. Takes some machining shills and a real good glue, something like “Gorilla.”
Yep. Anyone skilled in a machine shop can hollow out one nickel, and grind the edge down a bit on the other, then “friction fit” them together. Voilla!
We even get Lincoln cents put into Roosevelt dimes like this. Double denomination coin. A magician’s coin.
