Hello, I found this quarter while going through some rolls of quarters. I asked a friend who is a dealer, but couldn't find anything on this, and suggested checking on the forum. I don't know if it is an error or what it is. The possible error is an indent around the "D" mint mark on the front of the coin.
I don't seen any other damage other than some scratches on the surface of the coin. If someone could shed some light on it, I would greatly appreciate it.
