Looks like a Struck Through Debris, more than an Unretained Delamination. I say that due to the deep sharp angle hole near the 'N'.
Maybe it's a struck through unretained delamination from another coin? Lol. What ever was in the way it's definitely interesting.
I was actually thinking along those same lines. They do have shape to them, unlike cloth. Thin metal fragments from some source or other...
I’m at a loss as to how or what caused this. One one hand it resembles a strike though in all ways but on the other hand it resembles damaged. There is raised jagged metal on the edges. I’m at a loss.
I saw that too and thought it could have been a future delamination and the strike thru loosened the flake of metal only thing that comes to my mind
