I saw one better than that come back XF-40. I don't know what they do or don't see in coins like that, but the few I have seen graded, they usually rake them. If you are asking what I would grade, AU-55, maybe 58.
Don't know about the grade but that is a gorgeous coin. If it ever wants a Hawaiian suntan let me know. I'll give room and board
AU-58BN, i would judge to be about $10-$20 might go $25 it's more on AU side, because of slight blemish on Cheek and Jaw... If it wasn't noticable, then MS-60BN and then i would say $25 solid. Maybe $30... None the less, still a purdy gem!
