First impression: MS 64. Fields for 3 and 9 o'clock on the observe are marked considerably. Anterior curls level to eye show degradation and flattening. Reverse demonstrates more luster though I cannot tell if that is a rim ding near the "R" in the word "America." Strong dorsal wing and feathering with eagle definition though still more field marking that is distracting. Overall, good strike and beautiful luster with reverse looking better than observe but I think the field strikes held it back some. I don't mean to degrade your coin. It is beautiful!! I just think these threads more more fun and educational if others can see what each other is seeing for the reasoning behind their guesses. Again, she is a beauty!
Despite the tics, dings, etc. I'll go out on a limb and say they gave it a 64. (Because of the luster).
