Here we go again - slow day. Hopefully harder and there is a clue in the second image. What is the characteristic (dark mark) on the rim of the peace dollar? Answer Saturday or Sunday.
I don't know what it's called but a guess would be a broken piece of die stuck to the coin when struck.
Contaminated planchet. Not sure, but I would guess this would be considered a lamination all-be-it a funky one.
Alrighty - since my first thought was totally wrong how 'bout a solder mark from where a bezel contact was removed?
This is a detached lamination. I need to wait until Monday to post images of the missing piece. Clues to solve this GTC: The dark area is "into" the rims surface. You will see a thin jagged line from the base of the lamination running thru the "ST" and into the rim. This part did not come off yet. Notice the "raised border" around the missing piece. That's probably because it was removed roughly. Once the piece was removed the underlying surface can be seen. It is dark from oxidation. The image tomorrow of the piece will also be dark on its underside and normal silver color on the top. I'm going to try ONE MORE of these contests with a poll as they take too much of my time and that of the unnamed person SENDING THESE GTC's TO ME for my education and as a teaching aid that I'm passing on. Unfortunately, many take a look but few play so it appears not many are really interested in this type of contest. The only winners are those who play...no matter if their answer is correct or not.

I knew it the minute I saw it, especially in the wider-angle second pic, showing the adjacent lam. Definitely keep that piece that came off. Good documentation of this error-type.
Good eye @eddiespin I was going to mention that in the answer (the wide shot added that clue) but because of no interest....
