For those of you saying PMD... Check out this: http://www.error-ref.com/?s=grease Note the lines... OP's coin is struck through grease and is not PMD.
Th OP’s coin shows polish lines from cleaning, DDD and split plate doubling especially in Trust. Could this also be from: ? http://www.error-ref.com/design-devouring-die-wear/
Did you check out the link I provided? I think error-ref calls it "struck through die fill". I'm not sure of the "proper" term BUT OP's coin is not PMD.
