The coin has suffered severe Rolling Machine Damage. However, the MM may be different. I can't really tell from the pictures. Can you get some that are more close-up?

Looks like PMD to me, not sure but it looks like it took a hit or something.

You could improve your pictures tremendously by simply turning the coin right side up. Just trying to be constructive.

That is the stage of zinc rot where the affected area falls in on itself.

Looks like there is still a bubble inside of the D. You could give it a poke with a toothpick or just wait to see what happens.

The plating was split on the SE part of the mint mark. Now air is has reached the zinc, it is starting to deteriorate. This usually starts off as a raised area, then it starts breaking down the zinc, then circulation flattens that area. Not a pretty site.

Perhaps, but most of the sunken effects I see under the scope are accompanied by plate splitting. Generally, you can look through the split and see various stages of hydrozincite. It is possible it was a blister that split the plate and then sunk in.
