This crossed my desk today. This has to be one of the worst struck mint state or near mint state seated dimes I gave seen.... sheesh!
Seeing as how the coin looks to have extensive finning it sure wasn't wasn't because of a lack of pressure. My guess is that coin is a struck through grease error.
Limp sister strike. Whats with the die crack at the 4 o'clock position ? Looks like either a repair or electroysis.
I was going to suggest a strike made shortly after the dies had been inserted. The Mint didn't have the spacing and/or pressure correct. But I think the finning may shoot that theory down.
