Forum Shopping within grading companies

[orly57]

So this card has me drooling (currently on Goodwin at $7,500). It is gorgeous. The back doesn't bother me a bit. But you know what does? This is a 5-figure card (or close to it), in a psa 5 holder, but if this card goes to sgc, it is a 1.5 due to the paper loss. Correct me if I am wrong here, but that has been my experience both personally, and from my observations.
The lack of consistency within grading companies themselves is bad enough, but now we have astronomically large differences from one grading company to another, which results in forum shopping! The card has paper loss? DONT SEND TO SGC! That card is a 5 to psa, but a 1.5 to SGC. You have a handcut Bazooka Mantle or Ruth BigHead? DONT SEND TO PSA, because they won't give a numeric grade. SGC WILL! They are different companies, and have every right to grade cards as they see fit. But these huge discrepancies bring the legitimacy and purpose of the grading process into question.
