Found this coin the other day and I'm wondering whether or not its a error coin or just a coin that someone took a hammer to.
At first glance, the curvature over OREGON and the curvature on coin border are very similar. Can be a damage caused for other coins,but I can not tell you if it is during the mintage or a post-mint damage.
Excuse-me, the curvatures in OREGON and on edge of coin are very similar, can be a damage caused by others coins.
