Scot ReaderDave,
I have not compared prices lately but between 2003 and 2006 PSA slabs outperformed SGC slabs in the T206 space by 10-20%. More than anything, I think this was attributable to strong PSA set registry participation. T206 PSA 6-8 common prices have retrenched in the last several months due to some noteworthy PSA registry participants having completed or neared completion of their sets. This may account for any recent narrowing of the price gap (although I am skeptical that SGC has "taken the lead" in T206 pricing).
The issues to watch in the near term are (a) whether these PSA registry folks will hold onto their inventory and (b) whether more fresh PSA registry blood will come into the market. If the answer to (a) and (b) is "yes" then look for the price gap, if it has narrowed, to re-widen.
Bias Disclaimer: I like PSA and SGC and have slabs from both companies; however, the ratio is about 90% PSA and 10% SGC.
