JimB"SGC owns the prewar market"
This seems to me to be an obvious overstatement. Just to check my instincts, I went to ebay to compare how many PSA graded T206s there are currently with how many SGC graded T206s since this is the most popular vintage set.
878 PSA graded T206s on ebay
97 SGC graded T206s on ebay
These are not the totals one would expect to find for the company that "owns" the pre-war market. I am not making any claims about the quality of PSA vs. SGC. I personally use both companies. But let's have a little truth in advertising here. I am sure there are some sets where SGC has graded more. N172s might be such an example (I am not sure). But why don't we temper the hyperbole a bit.
