I just found a good example....
A. T206 W. Johnson, NO paper loss, rounded corners, SGC 30 / 2 @ $450

B. A. T206 W. Johnson, Paper Loss, nicer corners, SGC 10 / 1 @ $550

To make things more complex, these cards are offered by the same seller and he priced the SGC 10, $100 more. It seems like SGC weighted the paper loss heavily, but the SGC 10 is more desirable (at least per the pricing of the seller).
