I've never seen one this bad. There is a Wheat mark on Lincolns face and the shinny space to the left of Lincolns head appears to me to have the same profile as the back of his head and shoulder. Just rotated. Does anyone see anything else?
Glue several cents together with something like white school glue and break them apart. I think that part of what we are seeing is just damage.
Sorry, but your coin has some type of residue adhered to the surface. Over time the discoloration that occurred also discolored the residue. Your coin is not an error, it’s PMD
Everything you see as 'different' on your cent occurred to it well after it was already in circulation.
That's the last of your problems on this coin. That glue is real stubborn, too, if it's the kind I've come across. I think I had to use a crowbar on one of mine, I don't recall, lol.
