i found this coin and had to clean it up in order to see anything and wasnt sure what what caused it. On each of the pits there is like white stuff, then again i did clean it with tooth paste so that could be that. I thought it might be some type of coin disease. You take a look and tell me what you think.
Well, you can take comfort in the fact that you didn't reduce its value - it was already so corroded that it was worthless.
