the lower bit is clearly some machining metal scrap that got struck into the coin, but the two areas of extra metal near the top Im not clear what caused those.... interesting and Im wondering how much value added the error(s) bring? cheers, dc
First you should post both sides of the coin when you are looking for opinions. Second, I think what you are seeing is post mint damage. Metal has been pushed up on the surfaces.
I think possibly a combination of damage and a foreign substance stuck to the coin. The fact they are raised areas IN THE FIELD, should tell you something.
