I viewed this thread before looking at the same thread on NGC. I don't see anything in the OP of this thread that states it is a Morgan Dollar like I do over on the NGC forum. But now that I know, I will post what I wrote over there. The marks on the chin (blue circle by Jason) look to be indentations that appear to be evenly spaced in a pattern with a flat top edge and a rounded at the bottom of each mark. I don't know what caused it, but it seems to be either the coin was stamped with something or grabbed and moved by something that had protruding bumps like on a conveyer belt. Perhaps some sort of old time coin counting machine used in banks or casinos for slot machines. The marks in the field below the chin (green circle by Jason) are much finer and not in any pattern and don't look like bag marks. Looks like someone shot it with a really tiny shotgun. I have no idea what caused these marks.
I usually associate counting machine marks with circular patterns, but your theory does make sense. Insider edited the post here and basically ended it, because he got a whole bunch of clowns responding.
That is actually kind of humorous, never seen anyone do that before. Guess I will just watch the NGC thread then.
Don't give up @Insider ....there will always be a combo of serious and comedic replies. I see a combination of different causes like @physics-fan3.14 detailed in his post.

No need, this will be continued here again tomorrow with one less player.
This micrograph shows the chin and field under the chin of a Morgan dollar. Both the relief design of the chin and the flat field under the chin have two different types of marks INTO the coin's surface. What caused each?
OK, so I think I'm looking at some sort of pock marks in the field. Some are obvious hits from coins, but there are some that could be leftover divots from being struck through sawdust. The stuff on the cheek is a bit odd. Parallel lines are usually "roller marks" (draw bench marks) that aren't struck out, but they tend to be long, and not chopped up into uniform lengths. These could be some sort of artificial distress imparted to cover up something having been futzed with.
Struck through cloth Edit: it is from being in a bag of 1000 coins that was under numerous other bags in a vault and the pressure from the weight of the coins imprinted on the coin's surface, post mint damage.
I humbly apologize. These marks aren't very apparent, but they (blue) do seem to be parallel and in a straight line but don't seem to be repeating. The marks on the collar just appear to be from some kind of contact. Two questions, if I may...1) if you were grading this coin, would you notice the marks and 2) would you body bag it?
Insider 2, I for one appreciate your educational posts. I appreciate your many years of experience. I also enjoyed reading your articles in past coin publications. We miss you on the OTHER forums.
I see the standard bag marks but the blue circled are too regular to be just random. My thoughts possibly a feeding machine at the mint I feel they’re related to the minting process just like die polish lines and roller marks that weren’t completely struck out
