A while back I found this folded over dime and assumed somebody with a vise and some pliers caused the “taco effect”. For some reason I never tossed it. Yesterday I was reading an article on error coins and they showed one on a folded over planchette. I’d never seen one before. I’m positive my original diagnosis was correct BUT YOU NEVER KNOW. So bash me and crash me and slap me around a bit. Kid with pliers or a true oddity?
With the reeded edge all the way around, it had to have been bent after it was struck. I agree with the fire idea.
