Could be missing part of it's clad layer, but most likely saw a few minutes with some sand paper. PMD
Definitely not any kind of missing clad layer. Not sandpaper, either - there would be no way to do that so uniformly and neatly with sandpaper. But something definitely did grind the rim down there. It's machine damage of some kind. Definitely PMD. Post-mint damage. Worth one cent. Does look interesting, though.

Lincoln cents are NOT CLAD! They are "copper plated" What I see here is possibly a reject from being pressed into a lucky charm and it is most definitely Post Mint Damage. Having said that, I must admit the the Zinc Rim looks kinda cool against the copper plating.
I don't know how to explain this but it looks like mint error, the weight of the coin is 2.6 And the rim that you see is not something that you can easily make
But it is not. See how the edge overlaps the top of the letters? The letters were previously struck perfectly and now you have Zinc metal overlapping them. That would be damage.
