Found this Lincoln cent with a groove around the edge, sort of like a 2 cent euro but weighs 2.5. I think I've read that this cannot occur during minting so is this PMD?
I swear Dude, you find the craziest stuff. I'm 99.9% sure this is just Post Mint Damage of some sorts.
Is there an actual ridge that can be felt with your fingernail? Or is it just a stain like from being in a cup holder or something similar?
I seen those sell from a buck to a buck three eighty nine on eBay, but they were in much better condition than yours. Come to think of it I've seen a potato chip in the shape of a camel sell for $25,000. I mean, if you collect potato chips, too.
