You could send it to PSA. I am sure that the SGC 10 WOJO would cross to a 4-5 on their scale
Paper loss is damage no matter what, and SGC is not that inconsistant. They are strict and fair and this is the reason they are trusted by many collectors. Many collectors will pay for the fronts over the backs because thats what you are buying them for right?
the one on the left has paper loss and the one on the right is fully intact. Paid more for the nice front than the crappy front
