Hey guys, these pics sucks and I'll try to post better ones soon.
Anyways, I think I see an angle on unicoin's dime's "B" of liberty sharpening the top of letter.
I got a 1983 D dime with some thing going on in the same spot also on "E" "R". The top interior walls of these letters have an angle all matching direction. This reduces the surface area top of the letters and was hoping it could be DD.
Again better pics after weekend
