1951-D LWC Is It All Just PMD?

As I was looking over some of my stash of LWC I had a couple questions about this 1951D example.

On the obverse:

The damage to the 5 just looks like a hit to me. My other self was wondering if the hit would have moved enough metal or if maybe there was already a die chip there to begin with. I guess neither self will ever know.

Is the D just damaged or maybe an RPM with damage?

On the reverse:

Has the left wheat stalk suffered some kind of lamination?

Thanks!
