It's all about the hair on these beauties! VF - Lowest curl worn, hair otherwise distinct. F - Hair lines above ear worn; beads sharp.
This baby looks FINE to me. A few digs on face will detract a little bit too. The hair lines above ear and the lowest curl are worn flat on this copper. IMO, I guess you could argue that it is F-15, but it won't make it to VF-20.
I would not slab it...
