I have searched for any such irregularities to no avail, and I don't want to be a nuisance, but can anyone tell me if this would be classified as an error coin?
Thanks aicgsgrading. The coin is still in the us mint set box it came in. Doesn't look like it's ever been tampered with. What I was looking at was part of the relief of the Lincoln Memorial on the left wasn't fully stamped.
By the picture I cannot quite tell so question for you Is the spot in question just missing the frost or is it actually missing metal? If it' s just missing the frost I would say no and it was more than likely caused from a polished die If it's missing metal then I would say defective planchet or a strike through
I think a little area of frost is just missing. I would not call it an error...more a result of the proof die showing some wear. IMHO, this actually decreased desirability of the coin.
Thanks KoinJester. It actually appears to me that a portion of metal is missing. The beam on top of the pillars does not go all thee way to the end.
