In general prices realized are highest for PCGS, then NGC, ANACS and

ICG as a grading entity?

Because they consistently grade coins according to written standards that
have been around a long time. You'll very rarely see a VF coin in an ICG XF
slab. That bothers the crackout crowd mightily, and it's the crackout crowd
that decides who is big and who isn't.
