As a collector of T3's in SGC only I can tell you that I agree 100% with the previous post. Pinholes will NEVER garner more than a 20 and any back damage (paper loss, glue, scrapes or writing) no more than a 30. I have 40's with light creases (nothing thru both sides, back or front only). Corners or borders can have chips or small missing pieces up to a 40 and rounded corners up to a 60. Stains can get you between 20 and 40. As far a PSA, as usual, horribly overgraded. Any PSA will usually get a 1-2 lower level grade from SGC. My experience is SGC grades VERY tough on T3's, but that's why I like them, they are more accurate than the othe TPGs.
Hope that helps.
