Can anybody tell me how to distinguish this coin between a PROOF and a regular business strike coin?
I've been searching all over and there just isn't that much information on
Peace dollars (at least that I've come across so far). Please correct me if I'm wrong, but to me this coin looks very similar to the one that sold for $94,000 in 2014 at auction.
