7 times more ASM 252 CGC 9.8 on census compared to PP 64 CGC 9.8. I'm sure that number will go up if the price keeps going up but that's a vast difference in numbers.
There are plenty of this book out there. I just don't think people have bothered slabbing it yet. Before this recent pop there were NO sales of CGC copies of the book, but plenty of raw sales (at respectable prices). With that said, I don't know what the respective print-runs were.
Need to find my copies. Of course, my OO copy was read by my brother and I about 25 times each, so I'm sure that one is pretty rough.
Could be and I'm sure plenty of 9.6 will be cracked, pressed and resubbed if the price goes crazy but PP 64s have been $400 - $550 book in 9.8 for a couple years. Are you saying people have been sitting on them since $500 was just not enough of an incentive to get their high grade copy subbed?
