Randomly found this one in a roll of BU Peace dollars. There are a number of small, roughly squarish pieces of metal attached to the obverse. They appear to be silver, or at least a similar metal, as they have the same color as the coin's surface when rotated under a light. I tried gently prying a couple off the coin with a fingernail but was not able to detach them. Is there any part of the striking process that could potentially lead to an error like this, or is this likely just some sort of post-mint damage?
I know of nothing in the minting process that could cause this. Maybe they are glued to the coin. Have you tried using pure acetone to remove them? Chris
Most of the squares appear to cast a shadow, and some appear to be bent. I think these are a post-mint addition of some sort. If they were struck into the coin they would conform so well to surrounding geometry that there would be no opportunity to even catch an edge with your fingernail.
Thanks for the feedback. Nothing on the reverse, but giving it an acetone bath overnight and will check on it tomorrow. Yeah, that makes sense. I was looking at the two pieces in Liberty's hair and it almost looks like they match the contours of the design, but stands to reason they would be more pancaked if they were caught in the strike itself.
