I think this analysis is spot-on. I would just add that the trend toward PSA collectors at the higher end of the grading spectrum and SGC collectors at the lower end of the grading spectrum is self-reinforcing since supply begets more supply. Guys who collect the set in PSA 5 buy EX-looking raw commons and send them to PSA for slabbing and adding to their sets. On the other hand, guys who collect the set in SGC 3 buy VG-looking raw commons and send them to SGC for slabbing and adding to their sets. Hence ever-increasing supply of PSA 5s relative to SGC 5s and ever-increasing supply of SGC 3s relative to PSA 3s should drive more and more T206 EX collectors to PSA and more and more T206 VG collectors to SGC.
