Grading pre industrial coins is quite outside of my comfort zone however it seems like an easy answer - UNC. It's difficult to imagine a better preserved coin of that age. It looks like it was struck last week, which of course raises the question of authenticity. I have my doubts but would happily defer to someone more knowledgeable on the period.
Non illegitimis carborundum est. Excellent advice for all coins.

Nice coin with consistent circulation wear throughout upper devices and hair, ugly gash behind bust drops grade from (almost) AU to a solid XF.
No question of authenticity for me.
