I opened a mint sewn bag of 2023 Kennedy halves, and this was the first coin I looked at. A nice die crack from the E in liberty to the rim. I thought Oh Boy am I going to find a nice group of progressive die cracks in this bag! No luck! It was the only die crack out of all 200 coins. Bummer. I also found this damaged struck in coin. It looks like the coin took a hit somehow and a peeled piece of metal got struck into the coin between the T and the Y of liberty. Unfortunately, no other errors were found. This was better than my typical batting average at finding errors in mint sewn bags which, up until this, bag had been zero.
My friend. That's called a Rim Burr Definitely a mint error! Here is an example from my collection on the reverse of a Kennedy.. I hope this takes away your 'Disappointment'
I was on a train in the subway tunnel so I was typing fast any time I had a signal. That's how mispelled words occur..
