Don't call it an Error Coin until you first find out what it could be. I agree with damage. Reeding contact mark from another coin. No need to add a poll to your thread.
Is this coin worth appraising. I found it has an odd stamp not related to the coin. How did stamp get there. Thank you for your time.
Needs a photo for best explanation, but in general, most are made for personal reasons and not coin related. Jim
There was a photo I'll take it down and re do it with better picture. Thanks for the input I appreciate your time
It's damage. Let me ask you a question. Think of all the really nice things you and your parents have that are stored separate from everything. Maybe jewelry, fine crystal bowls and glasses, nice watches, rings, figurines, nicely polished sterling silver stuff, etc. Now imagine putting all those in *one* single bag and shaking it like crazy!! All that stuff would get scratched up, damaged, etc etc right ? Now think of coins. They are used for commerce. To buy thing. People put them in cash register bins, piles in purses, pockets, cup holders, the counting machines at banks and Looms (etc) distribution places pile them all up in rotating metal bins to count them, etc? They hit each other and damage each other. These coins are made for circulation .. for a reason, and as such, are used in circulation and constantly get damaged.
