Hello everyone, I wanted to share two pages from the same website that explains two different types of Mint Errors very well. Planchet errors - Centennial Auctions And Striking errors - Centennial Auctions In the striking errors section, they actually have a picture for reference of a coin that I own in my personal collection. This coin has been going around since before 2016 This is my slab - My apologies to those members who hate opening up links. I assure you that they are safe.
