I also think, rightly or wrongly, that if you have pre-war cards with beautiful fronts and slight paper damage or writing on the back, and you plan on eventually selling them, PSA is the way to go. I have just about had my fill of those great looking pre-war cards, even with blank backs, which have very tiny paper or writing imperfections getting downgraded all the way to "10s" or "20s" by SGC. But at least I know going in that they are going to hammer them. It is not at all uncommon to take one of these "10s", crack it out, and resubmit to PSA and get a 7 MK.
