Arrrrrrrrrg! Tweezers on a coin. Never post a picture like that on Cointalk! Looks to be PMD - Post Mint Damage The edge was struck to fold over the field. You can see the struck lettering underneath. And the exposed copper is also evidence of damage.
I only used the tweezers to get a better angle of the edge...i found this dime out of a roll from the bank we use at work..when you say "damage" from post mint is this coin worth saving or is it just a random dime that has no value in circulation ?
First, welcome to the neighborhood! This dime is not worth saving. The damage was intentional after it left the Mint. FYI - There are self-locking plastic tweezers that can be purchased at JP's Corner that are intended to use for dipping coins and taking photos like this. They only cost a couple of bucks. Chris
