I think the wear on the head definitely puts it into into AU range. XF seems too low. This coin is so visually appealing that a number grade wouldn't matter to me. Neither would I care if it had been cleaned.
Yeah, looking at the wear on the head, robe and arms I really wouldn't be surprised if it went as low as a XF40 although 45 is probably more like it. But the reverse seems to have less wear than even some lower-end AU's. It is a beautiful coin regardless of the final grade. I really am torn between Xf45 and AU50 but I think I'll settle with AU50 because of the strong reverse and nice overall appeal.
I'd say AU-55 , these weren't the best struck coins and the eagle is pretty full . An MS grade wouldn't surprise me .
