Aloha, is this your classic grease filled on the obverse? Or is that over polishing of the die? Looks like a die chip on the top of the seven rt. corner. Maybe something going on with the mm d. I know I got to get a closer pic I'm working on it but when I seen this coinroll hunting. Didn't know if it was one or the other. Hard to find grease filled online even a variety Vista or copper coins. Reverse looks like some machine doubling going on Thanks in advance
Die Deterioration Strike. Struck through compacted grease on the Die did not allow what you don't see to form. Mint Mark is probably a circulation hit.
Something to look for on struck through grease (greasers) is a fully formed rim, missing details, and weak devices.
