"Peter its systemic nothing is ever going to change"
Then why even have grading? If an A is the same thing as a 10 (and it's deemed ok to transform any card into a 10), then where is the need for a TPG?
And why is the valuation of a card graded "10" any higher than the one graded "A"?
That logic would dictate that the prices realized should be about the same for each.
