This is a new one to me, Most likely PMD,But strange enough to post. The weirdest part is the indent around 60% of the edge. Sorry about the blurry edge pics. Any thoughts are appreciated!
Let me guess, you got a roll of Jefferson nickels and then took a hammer and other tools to them? LOL
2MH - one of the first things to realize, when you are searching rolls or change for errors, is that just because a coin 'looks' different doesn't automatically mean it's an error coin.
