exactly, maybe it is a dent on the die instead.

I'm pretty sure it's a Die Chip, since it's raised. Looks too large and round to be a Die Dent. It's definitely a weird one.

I agree that the gap around the mint mark is unusual. A die chip should reach the mint mark since it's a weak point and incuse on the die. A die dent wouldn't respect the boundary like that, it would be right through the mint mark, too. Even hubbed in debris would touch the mint mark.
An odd anomaly, for sure.

Thank you, Brandmeister for commenting. It's a weird oddity for sure. I could be wrong and it might not be a Die Chip. If it is a Die Chip, then it's the most unusual one I've ever found.   Errers and Varietys.

I started thinking it might be a die dent as well, but after looking closer (especially the date in your second image), I'm inclined to think this is some extreme Die Deterioration, like die subsidence(?). Do you notice any design weakness opposite the anomaly? Words of encouragement are one of the major food groups.

It's not a die chip. It's a form of Die Deterioration. It might be a "bleb" (die erosion pit) or represent the beginnings of a "design berm". In any case, it's not a form of brittle failure. Here's a much more advanced case.  Error coin writer and researcher.

Thank you, Mike Diamond! That mystery was finally solved. I'll relabel it as Die Erosion Pit or "Design Berm". Errers and Varietys.

The 1985-P dime shows a design berm. So, I suspect the lead-off dime is an incipient design berm.
