This dime is odd in the sense that if it was just a badly worn dime it would be almost unrecognizable having over a gram difference. It also is super thin and if the edge was cut off post mint it would have to be pounded down to reach this thickness. I’m lost on it.
From the porous surface I think it could have spent some time in an acid. the lack or rims pretty much tells you the edges were ground down.
DEFDAM - Definitely Damaged That's what a clad dime looks like when it is corroded. Yes, it can occur. Not a mint error of any kind. Whoever voted for Error in your poll must of done it in error!
Yep, the rest of it has been dissolved away. Edit to add: Welcome to CoinTalk! Paying attention to your change is a good first step...
