That is my kinda coin. Worked for a living and still looks great. I'll giver her a low grade "fine" just because she still has a lot of detail in her hair.
To me, the obverse looks VF-35, the reverse looks F-12. It has an old cleaning, but that's generally acceptable for such an old and circulated U.S. coin. I guess VF-25.
Does the Eagle wear differently on the B1 compared to other varieties? I thought the Eagle made the 25 grade. It is Early ANACS, I should have graded a little more conservative.
The hair detail is clearly in the vf20 to 25 range (check pcgs photograde). from what I have seen of the small eagle dollars, the reverse almost always seems 1 or 2 levels below the obverse. I agree it probably had a cleaning in the past, but it was lightly done (no hairlines) and has retoned pretty evenly overall. Bowers, in his silver dollar tome, estimated 35,000 small eagle dollars struck in 1798 compared with 200,000 large eagles. There are 2 varieties, 15 stars and 13 stars, with the latter being more common. He estimated a population of 700 to 1200 for the 13 stars. I'll need to study it a little more to evaluate the die state. A pretty scarce coin and hard to find a decent example in a low to mid grade.
The obverse sharpness grade is better than VF-20, but the surfaces have issues. The reverse looks like a Fine. It's been net graded, but it's still a respectable early dollar. It looks like someone tried to give it a coat of silver paint at some point. The 1798 Small Eagle Dollar is a "better date." This was the switch over year from the Small Eagle to the Heraldic Eagle. Here's mine which is PCGS graded VF-35. There is a 13 star and a 15 star variety. Those are the only die pairs.
