I agree--I had said 65+, and it got the bump to 66. Definitely agree with Paul's evaluation that it could as easily have been a high in grade 65 (that is why I went 65+) or get that extra bump. Nice coin, no matter what, and good pickup.
It looks like a VAM 3A. Someone else can chime in, but you could put that in your listing. Someone might be looking for a high quality example of that variety.
My call a high end 65. I'd say 65 with a bean or a 65+. I'd not pay 66 money for it either. But you paid 63 money so nice score
