So I was searching threw some change and I found this sorta interesting. I wonder what happen to it. Sent from my iPhone using Tapatalk
What happened is that it was struck with a broken die. It's commonly referred to as a cud. A cud only involves the edge of the coin. Yours has been bounced around a parking lot for quite a long time.
It looks like something bumped Jefferson on the head. It's a keeper, for the reasons aforestated. That's a wonderful find.
