Looks accurately graded to me. Gradeflation has turned this accurately graded 65 into a modern overgraded 66.
I agree with the grade too. There are some small imperfections/disturbances in the obverse fields. There aren't many, but IMO, too many for a 66. There is a similar disturbance on the reverse fields at around 4 o'clock. It's a very pretty coin. I really like that pull away toning around the stars and date on the obverse. It looks cool.
