I'm still here... I'm trying to get a better angle on the "D" As I noted in the first image, it is SLIGHTY (very little) raised on the right side of the "D"
Just Lookin' I've looked myself crossed eyed before. Is that a Dent, Dollar, inside the D or is it flesh with the field?
It's damage. The reeded edge of another coin creates this kind of thing when it smacks up against the field of a coin.
