T206Collector...involved sending 40 PSA graded T206 cards, grades ranging from 2 to 6, to SGC. All of them were uncapsulated -- that is, I did not crack any of them out prior to submission. 30 were returned to me at the same grade or higher -- a couple of 5's became 70/5.5, and even one or two 4's became 60/5. 9 were rejected as not meeting the minimum grade and 1 was rejected as having been trimmed.
My best result is below:

This is not typical, of course. And when I picked up the Cobb, I thought it was more of a 5 than a 4 -- bought the card, not the holder, and SGC ultimately agreed with me.
