I'll go with 45 or 50. I'm not sure what the grading services will think about the spots on the obverse.
It's hard for me to tell from these photos, but I might be seeing luster in the fields on both obverse and reverse. What are you seeing in hand?
There is a bit of luster. I bought it on eBay. Here are the seller's pictures. There is a touch of cartwheel affect.
Not sure if it’s been cleaned or not but I don’t think so. Hard to tell from the photos. As for condition, I’m at F-30 to a 35. Too much wear her her toes and high spots and her right leg drapery is worn.
