This one has a line going vertical through the middle of W in we,and branches out with a couple lines through the hair The pictures are not very good,but maybe good enough to see.If so,could this be a mint error,and what caused it.So far i have found 9 with the same mark(after going through about 10 rolls)
I don't think it's a mint error, I think it's just a hairline or a post-mintage crack that happened as the coin was cooling off, nothing special. A die crack, which is a mint error, would have had metal bulging out in a relatively small area, the metal looks like it was cracked after the coin was minted, which I'm not sure how common it is, but it's considered to be post-mint damage and therefore, probably isn't worth much
Since the die crack is part of the die, finding several would be normal. Several collecters feel as the mint does that this is normal wear and not an error.
