Robert- you don't have assume anything regarding whether or not the cards will cross at the same grade. You only want to get as much information as is out there, then decide how you wish to proceed.
Of course we can never be sure how a card will do in a crossover. But let me say this: if you were to pay a huge premium for a PSA 8 because it's purportedly the highest graded, and there's an SGC 9 in circulation, even though you and I don't know with any certainty how that SGC 9 will fare at PSA, you have to be thinking that there's a pretty good chance your PSA 8 is not the best one out there.
