thanks for the post, a question for you:

Your table lists the average SGC grade at 46 and the average PSA grade at 4.5. This is about a full grade higher for PSA graded cards. These numbers may lead one to believe that PSA is an easier grader and gives higher grades while SGC is harsher. Different from the Goudeys (see the thread that Jim Crandell started), there are more cards graded by SGC than PSA, so the PSA supporters wouldn't be able to use the argument of "high grade cards only go to PSA" (actually this made sense to me for the Goudeys).

From your post, it is clear you have seen many N172s in your collecting lifetime. What is your general thoughts on the toughness/easeness of PSA/SGC grading? I'm not trying to make this into a battle between supporters of the two companies, but I'm genuinely interested in your thoughts.

Also, how did you adjust the PSA cards with qualifiers? For example, how did you average in a card that received a PSA 7oc?
