That is DEFDAM - Definitely Damaged Someone very bored made notches on edge of the Cent. Why? Only the person who did it would know. Not a Mint Error.
clearly damage / PMD. looks like someone was trying to make the edge look like a dime. But probably got tired due to the effort needed and gave up.
Paddy, I think CoinRoller, Profit Man and Josiah Rush should be locked in the same closet together. Chris
you should be able to make one better than that. use a single cut file as the edge die, and push/roll a penny across it. You may have to use a light mallet to tap it down as you roll it to get the entire edge well defined. That would be a lot easier than whoever did that above.
