Looks like a clear finish on one side of the coin. When squashed in a vise, then the clear finish cracked like glass. People murder coins all the time. Trying to [create] a mint error. But when they realize it doesn't look like an error coin, what to do with it? Spend it. Then they end up here when the next owner finds them. (We have seen some duezies here. (Sorry I had to create a word there. LOL)
