    Wondering if this is post mint damage or some form of error at the mint. I haven’t seen anything out there like it yet, which makes me think pmd, but the appearance is odd enough for me to ask.

    Looks like a slightly misaligned die strike. That would a caused a bit of a finned rim which would make it look raised and bigger on one side.

    If you are referring to the edge, it may be that the copper core has been eaten away partially by some sort of acid. I've seen this before on clad quarters, but this is the first time on a half dollar.

    A very slight MAD.

    I was mainly referring to the edge. It’s almost as if the center of the edge was ground out full circle, leaving a raised edge on both sides. For pmd, I would think that the center edge would be smooth are altered in some way, but it maintains the rib just like the raised sides. I see the slight MAD.

    I’m with Chris @cpm9ball
    Unusual surfaces and copper core eaten away is a tell for chemical damage

    OK, who left the proof half dollar soaking in an acid solution?
