BTW, the term is PMD (Post Mint Damage) or as one of our resident error collector terms it " DEF DAM ".
I think I was referring to situations such as with this old, somewhat ill-used penny, when I recently made reference to "hallucinatory mint errors". If I'm not being nice enough about this at this sensitive time of the year, it's because I'm a grouchy, old squirrel fart.
