davidcyclebackAre the PSA/SGC grades 1-10 accurate for what the grades are supposed to represent? Is there a point where SGC is calibrating it's 7 to match or 'better' PSA's 7, and visa versa, that a company's 7 no longer represents Near Mint?
Do collectors ever feel that, for a grade or condition, that a company's grade no longer, or often doesn't, represent what the grade is supposed to be, perhaps due to numbers competition with other companies?
What does the change in a grading company's standards over the years represent? (ala a PSA 7 today is different than a 7 12 years ago).
Irrelevant to alteration issues, what does the Wayne Gretzky T206 Honus Wagner having the same numeric grade as in 1991 represent? Does this represent consistency in grading or how numbers, number scales and comparing number scales is in and of itself a commodity?
Beyond authentication and alteration detection, should a grading companies' main concern be how it's numbers line up with the numbers of it's competition?
What does PSA collectors liking the toughness of PSA grading, but resubmitting cards for higher grades represent? Is it that they like the perception that PSA is tough?
