Hello everyone, Looking at my world coins again, and found this coin that I think has cud? Not sure can someone tell me what makes a coin turn out like this? Thank you
Hmm, that almost looks like solder... or perhaps a glue like Mat said. Maybe try giving it a soak in acetone (not nail polish remover, but pure acetone).
Looks like a bit of solder to me. It’s either a cud or it isn’t so your thread title threw me “a lot of cud”. I thought you left out an “R” and it should be crud. Lol
