coffeecup57, I see on yours, that the rim is affected. It does not appear to be on mine. Makes me question if mine is delam or PMD.
I am no expert on these,but would guess the rim is not always affected.I can not tell from the photos if yours is or not.
Nothing to do with your photos,just my eyesight.

Definitely more extreme than mine
Yours affects the obverse,which is always cool.
