Look at the edge of the coin? You should see a wrap around piece on that edge. Looks like a struck through debris issue on this one from what I can see. Not a lamination issue, as they are flat and on the surface of the roll stock. it would be impossible for this to be a lamination if it wraps around the edge of the coin. A
Rim Fin would not be that large to cover both edges of the coin's faces. So I'm sticking with the debris issue on this one.
