1998 LMC Penny / Die Dent

Hadn't thought of that. There is a light clash mark in bay 4
But, I'm still thinking die dent: There is also another "anomaly" which runs from the center of "U" in unity through the "O" in one. Can see a slight refection of it in the full reverse, but it was too faint to photograph separately.

The top section (to me) definitely looks more like a die dent. The bottom part, into the T of cent has me wondering (there are certainly some polish marks there). But it seems to affect the T, not just go under it. A ribbon could, theoretically, have been push into the die to affect the T

(p.s. If I sometimes seem argumentative, I am just thinking "out loud", trying to process some of the proposed possibilities. )

I'm leaning toward the die dent/doink explanation. Would be fun to examine this one in-hand.
