I actually like it @ 64+ BUT since u dont have that option, Im going for the win....>>> MS66.....FINAL ANSWER..
Well i believe they grade the 80&81S tougher than any other date... (speculation on my part)....W that said it looks better than a 64... and that 83o looks like it would barely eek out a 66 but it DOES have an unusually sharp strike...
No doubt... people think im nuts but i prefer small white anacs over edge view ngc any day of the week....
