Are there any known errors for the 2018 silver proof?
Don't know if it happened a lot on 2018 silver proof sets but mint errors happen quite a bit (much more then you think) in proof and mint set in general. In addition, coins that have been damaged (
PMD) and put into sets (at the mint) and mailed out. How do I know? I have a few.
