T206Collector...because it was the first SGC 60 Southern Leaguer I could find that has sold on ebay in the past few months. I'm not going to dredge up others, but a PSA 5 Thornton also sold on ebay in the past couple of months for $400ish.
My only point is that it is as easy to find examples of PSA selling for more than SGC as it is to find SGC selling for more than PSA. Examples of SGC 60(5) southern leaguers, which rarely come to auction, don't prove much in the abstract. I encourage you to look at VintageCardPrices.com sales of T206 Cobb Red Portraits -- perhaps the most abundant and regularly traded T206 card. You will see SGC selling for more than PSA on a regular basis.
In my experience, I have never been able to get a meaningful discount on a T206 card because I was collecting the set in SGC holders. BVG and GAI? Yes, absolutely. But not SGC.
