take a look at the last major auction from Heritage - there were N162's in 6's and 7's with front and/or back paper loss. I could only bid so high on a few of those cards on my list out of over 50 cards listed because I wouldn't be able to cross them to SGC even close to the same grades or at the very least that was my fear. I need the uniformity within my sets as I'm OMG - now known as OCD - but when I was a kid in the 1950's I only heard OMG........ SGC is more rigid about such loss in my experience. Recently purchased an N162 Anson PSA 2 with 3/4 POINT of a pin sized spots of P/L. It just shows a level of inconsistency. I'm crossing it and could care less about what they grade it. It's a beautiful card and for me the grade is only relevant when one goes out into the cold world of commerce and finance as a motivated seller.
In fairness I believe it's just a question of what criteria the particular TPG uses and whether your hierarchical priorities are aligned with theirs. One might think centering more important than whatever - doesn't make them right or wrong.
I'm not really comfortable with the number of cards the major TPG's make significant mistakes on but they offer a service people seem to want and are likely getting it "right (whatever that is - "I sent in my dog-eared card that I love and it got an 8! I LOVE my grading company!) most of the time. In reading Joe Orlando's comments about HIS graders - it's clear they are often spending as much time grading a 2001 foil as an E90-1 - a few seconds. It's a rare bird that can effectively evaluate such different cards and in addition I'd like a little more attention paid to my cards details rather than a cursory glance - I would think due diligence implied in the service I'm paying for.
The big boys process a great deal of cards - graders often rendering opinion in seconds to accommodate the volume - and it's subsequently proffered and sealed er entombed along with the card by nameless souls with unknown qualifications - undoubtedly barely of voting age and likely unfamiliar with many of the older cards and the nuances. OK. Done venting.....
