I don't know if this is post mint or legit errors. I can't even make out a year on the coin. It's super thin as well. Thx for the help.
Sorry,but it was damaged after it left the mint. It was pressed with something that had a lot of tonnage. The back looks like it was part of a sandwich with another coin in the press. Not an error
Appears to have been run over by some type of rail car or metal roller on metal track. If it was as heavy as a locomotive, it would have smashed it a bit more. So something along those lines but a little less heavy in weight. The direction it was rolled over from looking at the obverse, the coin was run over starting from the bottom and up to the top. I know because when I was a kid, we used to set coins on the railroad tracks and watch them get run over by slow moving trains. Plenty of experience in that department..... Got the idea from watching reruns of the Andy Griffith Show, a coin run over by a train was supposedly a "good luck coin".
