Photos are to blurry to get the details. It looks like die deterioration. One thing is the 71s you posted is a proof. The coin you have is a Bus. strike. It in no way matches an FS-101.
Sorry about that I was in a hurry this morning trying to get around for work I'll match that up on my lunch break
I know this is a penny forum but I could not find the right one. Bought this Peace Silver dollar and in looking at the date I noticed the 2's may be doubled. Opinions??? Sorry about the lights. Scope is messing up.
Just when you are looking at these variety's all the features must match up. You start with, Is it a PF or a BS strike? Then you look for the Mint mark placement, second Check. Then start matching up the doubling and see if is the right class of rotation. Each of these dies are unique and can be identified by the smallest of die scratch, die chip, etc. Remember if the MM placement isn't correct, it isn't the same Variety.
