MarkAbout 3 months ago, I submitted an n172 ned williamson to GAI with scrapbook removal that they graded as authentic. It's similar in condition to the cards in that 116-card lot on Mastro that sold more than six figures - it seems there would be a high demand for a service that authenticates n172s and other rare cards even if the backs of such cards are gone.
I also own a PSA "Authentic - Trimmed" 1954 Wilsons Franks Ted Williams which is only about 90% intact. I wonder if the missing 10% would separately grade.
