I just found this 1971-D Half Dollar with a few interesting features, I'd like to hear any thoughts about the cause/s of these.
I'd like to see a better close-up of the indentation next to the "I". I don't see any indication of "crater effect" so it could be a strikethrough. Chris
A closer look at the other area in the field between "L" and his chin doesn't look like PMD to me either. The luster inside the indent matches the surface of the coin, there is not much sign of circulation damage on the coin anywhere other than a few tiny nicks and scratches, and the reverse shows no sign of opposing a blow to the obverse.
