Could someone please tell me what causes the surface of a coin to look like this? I have a couple more like it and then a couple that look like someone ran a paint brush over it.

This one is similar but has a bunch of bumps on Lincoln’s neck, forehead and then all over the reverse. Gas pockets? Chickenpox?
Modern cents are plated with copper. What you see are plating defects that are very normal. Spend them.

It’s an issue with the copper plating. When it doesn’t adhere properly to the zinc core, it can result in different odd textures from straight lines to pimples or blisters.
It’s quite common from 1983 into the early 90’s in both MS and Proof.

Nice zincolns with nice flat surfaces and no carbon spots can be almost impossible. The toughest is the '84-P. The '88-D is easy in the mint set.
Spend it, no other value 👎
