1970 S roller lines, pmd or something else?

This was a red 1970 S. I don't believe I see any wear, just the strange surface marking. The memorial stairs especially look strange since they are all uniform. As always just learning for this one since I've seen similar ones in the past.

And happy 4th of July

Putting my money on a fingerprint behind Abe’s head. Looks like the same kind of corrosion in front too, just not enough there to say fingerprint or not. Not sure on the reverse….

 

Definitely a fingerprint on the obverse. That dark it’s etched into the surface of the coin. What a shame.

 

Abrasive cloth marks on the rear. Fingerprint perhaps on the front.
