    Hello, I'm new to this forum. I collect coins, but sporadically. Since I buy my stuff at flea markets and garage sales, I'm reluctant to try buying more expensive coins, because I'm afraid they're fake...

    I found this coin in a big box of foreign coins. The eagle side has an unusual roughness to its design as well. Is it an error coin?

    Zinc is a very reactive metal. It is very susceptible to corrosion like what is seen on the eagle side of the coin. I am not 100% sure but the bubbled look on the other side is also a result of corrosion probably internally and it is what plagues Copper coated zLincolns A gassy planchet.

    Thank you! Is there any value in this sort of error, if that is what it is called?

    It's not an error this is all damage.

    I think it is defacement of the die so it could not be used again, but I guess someone did.
