I like the sharpness of the stars, but I see a fair amount of wear on the reverse. Even knowing that these coins tend to have weaker reverse strikes, I am leaning toward F15 details. I believe this grade is proven also in the wear in the curls on the obverse. The clasp looks relatively sharp, but there is definitely wear in that area also.
The graffiti on this coin is a real shame. Even so, I think it's a beautiful coin and would proudly include in a collection.
