Not sure which parts you're puzzling over, can you point out what specifically you're uncertain about in these pictures? I'm no expert, but besides wear from circulation, I'm seeing what appears to be a combination of
Mechanical Doubling and
Die Deterioration, though I could certainly be wrong.
On 1980 I can't see anything but wear.
LIBERTY appears to have MD shelving on the T; looks like
PMD spreading the B and R.
N GO of IN GOD looks to have some MD directed toward Lincoln. I might be imagining a slight
Die Deterioration Doubling directed toward the rim.
I can't see anything unusual going on with WE.
Also not sure what you're seeing in the reverse pictures.
Not trying to dissect your post or anything; my intention is just to give specific feedback since there's a lot of stuff to look at. Hope that's helpful to generate some discussion, but please elaborate on what you are looking at. =)
