Jolly - My understanding is that machine, whatever it is - is only used with grading super expensive cards. I doubt they use it on every single thing they grade; SGC only had one of them, at least in the video I saw. That thing was very suspect. They had a '53 Topps Mantle and the surface looked fine under normal light, even twisting it around - no creases, no wrinkles. But suddenly under the machine they can see a flaw "inside" the cardboard stock? Sorry that's BS.
