So I have a 72 D that looks likes it was almost missing the FG. It's so weak and blurry.i say missing FG.thr G looks like a circle ⭕ from far away no F. The 79 looks like it is missing the most ng mark. Like it was made and the guy forgot to die punch in the letter. It's marked on there were the P would be. Well here the pics.
Looks like a 1979 from Philadelphia, hence no mintmark. The FG is weak and may be a partially filled die. Nothing rare.
Looks like 2 copper SCRATCHES(maybe rust) in a z like or n like position at 55< or more.it looked strong. So the coins were minted with the stamp on them already.?
