Scott- I think there are other factors that determine a sale price other than only whether or not a card is graded by SGC or PSA. I've seen an equal number of SGC cards outperform PSA cards of the same grade, and it has a lot to do with timing, and who is bidding at a given moment, among other factors.

It's not a linear process; not every PSA card outperforms every SGC card of the same grade. That's an oversimplification, and it's inaccurate.
