i have a vermont quarter(2001) where the mint is usually P or D is has an S does anyone know what this means?
Well, it could mean "silver" , but then again I'm betting it means San Francisco, California where it was minted.
Well, you don't expect to see Proof coins in a bank as they are not issued for circulation. They are sold to collectors. But every now and then one will make its way into circulation until another collector spots it - and then it's gone again.
