PMD ( Post Minting Damage)
Jfantnj- Everything you have been posting is just circulation damage of one sort or the other.
Things like gouges, dings, scratches, broken letters, worn letters etc. are nearly always damage. It is only an error if it happens during the actual striking of the coin. Instead of looking at everything as an error, look at it as damage and then ask yourself is it possible for this to happen when being struck. Most of the time the answer will be no. Look up one of the several websites on what an actual error is and you will see the difference. One that I use is “error-ref.com” It’s a lot of reading but also a lot of information.
