The area spot on its rev is like a foreign object lay as between the die and planchet. Like a clear very thin film, like selifanin.
Wow! Nice. Didn’t think it was FS, but NGC busts chops for FS. 66 was a definite possibility. I almost said 65+.
I was also thinking 66 5fs on the holder with a personal grade of 65 5fs (lower by one based on the smear on the reverse-which I later saw in the comments was actually on the slab). It's funny to see that Ed Wood still gets brought up.
I was going to say 65 5FS. There's enough weakness on the lowest step that I'm not a huge fan at 6FS, although I can see why they'd say it.
