I think it effects the price some. But you get a return for taking the risk of doing the CT removal and getting the blue label. This isn't as recognisable a book but it lends some credence to this point. Slight ct on a 9.0 Strange Suspense Stories 19 originally sold for $3120. 10 months later the same book sells in the same venue as an 8.5 blue for $11,400.
