SGC started doing it so that people familiar with PSA would ahve something to relate to, but I gaurentee you, as others have mentioned, a card that gets 5 on the SGC scale will come back with a 6 or better from PSA.
Short term, yes, PSA sells better and has better market share than SGC, but if they continue as they are, this will not be the case in the long term, especially for vintage cards. It was pointed out that the major auction houses carry mostly PSA cards. I am sure this more a function of the fact that there are more PSA cards out and not out of preference for one company or another. I don't think auction houses really care what slab it is in, as long as it is not PRO, AAA, NASA or some other disreputable service.
