I bought this coin a couple of weeks ago - it came in a large lot of U.S coins. The photos were taken in direct sunlight, so this probably accentuates every minor surface detail/fault. Still, how would you grade her? If somebody can throw in an attribution I'd be more than thankful.
About VF-30 to 35, I'd hazard. Maybe an old cleaning and I'm suspicious of what appear to be hairlines on both sides but primarily the obverse.
Right in line with @Publius2 . . . I think I'd grade it VF35 if I were selling it, or XF details if an in-hand examination convinced me it's definitely cleaned.
Sunlight tends to be very harsh on coins - every little scratch shows up. My interpretation of the scratches are consistent with normal wear, I don't see cleaning/polish lines. I'm more suspicious of the dark spots which might just be normal toning, but might be some sort of environmental effect. And, I concur with the VF-30 grade.
These very early Large Bust Halves are almost a stand alone type of coin. I see a prettty nice clasp and significant detail on both Liberty's hair curls and the reverse eagle's feathers. I would guess a grade of VF-30 but will admit many others will have more experience than me. I could be off by a full step in grade. Very nice coin though and i think you are lucky to have her. I find these Lg. Busts very impressive in hand. james
I just read the other replies. I feel better knowing I'm in the same ballpark. I don't know what to say about hairlines or chances of straight grading. James
