Hey I’m new to coin hunting but I found this penny that has a weird stain on it that looks like it came from another penny. Any idea how this would happen or how to remove it so I can see where it was minted?
It looks like zinc rot, but those copper pennies can't have zinc rot. Maybe it's just very old glue residue. Also it looks like an 1944 D, which is a common date, but still a keeper.
I personally don't clean coins but some of the members here on cointalk swear by bathing it in acetone. Dave
Looks like a common 194? With a paint stain. You can't hurt the coin by using paint remover on it. I normally would not recommend this as is damaged the coin but it's only worth about $.02 to begin with and no collector would want it with that stain and the black spots.
Agree on the paint. I think if it sits in a small glass jar with acetone (and a lid) for a couple of days the paint should rinse off with water. There's really no value here. You'll be using 25 cents worth of acetone on a 3 cent coin.
Edges are fibrous, may just be where it was stuck to some paper or something. A soak in water might work. If not try acetone. And it appears to be a D mintmark.
