Fire or heat damage? Really? Maybe I should leave it as is. At least it's an AU. If I ever scrape enough for a problem free already graded example, I'll pick it up.
I know one of those rings is the reflection on the camera in the holder. But I think I see what you're talking about.
The Draped Bust sure looks original , though not sure about the Busty . Love your 1806 especially the no stem through claws !!!!!
Interesting thought - here's a different, more recent pic of the capped bust - to me, the coin looks more original than in the first picture I posted - not as bright in the middle and more charcoal, less blue on the edges. Pretty consistent with other old silver with CAC certification, which this one does.
And a better picture of the 1806 half (didn't CAC - maybe because of the dings?) I might try taking it in again - in person:
