Definitely post-mint damage. Study the info at the site Sal posted to identify true mint errors. @SensibleSal66 Also, study the minting process and how dies are made at John Wexler’s site (doubleddie.com). Learning from these 2 sources will save you tons of time and money and help you become a better collector. The minting process produces coins in a finite, well-documented procedure. PMD occurs in an infinite number of ways that, sometimes, only the person who did it knows how it happened. Study and research will enable you to learn how to tell the difference… @Dale Adams
Dale, how do you post from inside jail? Just kidding, but your avatar makes it look like you are in jail. LOL
