This penny came from a lot I found in
ebay. The initial purchase was not for this coin but ounce in hand, I got questions about it.
A large portion on the reverse is cover by a kind of snowflakes. Depending on the angle, they are less or not visible. Some of them are found too on the obverse in a smaller proportion.
It was label PL on the 2x2 and it's really not a circulation strike. Is this coin are affected by an environmental condition or stike through something (grease, water, small brush wires or something else)?
Thanks for your help!
