1958 error

I know this is supposed to be for dug coins, but I wasn't sure where to put it . I'm thinking it's a stuck piece of metal on the coin after looking at it through my loop. I know what a die crack looks like and I know this isn't that. I just need a 2nd opinion.

hey Sal it looks like its either a die crack or it was stamped over some cud but i'm leaning to die crack

Um I have to disagree Dan. If you look at it in person you can see it's a extra piece of metal now that I've looked at it again more closely. You can see where the metal burr at one point looks twisted. I say it's definitely a Metal Burr from when it was either Puched out as a blank or when the Rim was made slicing a Burr that settled on the Coin. Or it could of been placed there or a piece of metal flew on top of the coin. Either way, It's probably not worth a real lot since it's a Nickel. I'll send a pic to a contact I have.
