I just got this coin today and it's still in its OGP holder, which I'll be taking out of. When I flipped it over to see the reverse, I saw strong "scratches" on the bottom right. They seem to go in the same direction as the flow lines. Are these marks as a result of die wear, or would it be PMD? It's a bit hard to tell if they're raised or not. Thanks in advance!
This one was priced right. The striations in the field, are usually some sort of mechanical error. They are only visible on the reverse of this proof also.
