Well I checked the three sites we often use and none have a listing for the 1983-D
. There are several for the 1983 plain cents. (Philly) So I feel there is probably not a DDR
on your coin. But to tell for sure, We need images close enough to see what you are looking at. About these size would be helpful:
Those sizes will help us see if there is something there or not? You mentioned errors. Doubled dies are varieties, not errors. Damage to a coin is not an error. It means that the coin was damaged after the strike. Cleaning a coin does not make it an error, it was altered after the strike. So you might define what it is exactly what you are seeing?
