based on the photos I think its graded correctly maybe on the lower end of the grade, I just picked this one up do to the clashing. I am not sure the vam and probably no way to identify based off these pics. I can post some close ups when she arrives.
I think it's a nice 64...but based on your statement that it's "low end" for the grade I'm going to say it was graded as an MS65.
It is so on the border between 64 and 65. I was gonna say 65, but I have guessed too high recently. lol
I was honestly going to say MS64...then I read his post where he said it's "lower end of the grade." I would say this is a strong 64...but if it really is lower end of the grade I figured they called it a 65.
