Ok, I'm pretty sure this is not a detached lamination (the raised grooves are strange), but what is this? Just some weird sort of PMD? I would think that somehow the cent got sliced down the side and then the thin slice broke off, but then why is that part elongated away from the planchet? I would think it would be mashed inward. I don't know enough about the minting process to see how this could have happened in the mint - I'm thinking it didn't, but I thought I'd run it by you guys before I decide how to label it. Just to make sure this isn't "The well known 'cent got stuck in the press and stretched'" error or similar. Any thoughts? Thanks!
Into the smooshed folder category it goes, then. Thanks edit: You know @Beefer518, you're right. That part of the cent is completely flat, the letters are not raised at all. Mashing/smooshing it down like that would definitely stretch the planchet... Ok, as paddyman would say: DEFDAM. Thanks for the insight!
