I think you would just need a "mold" card, ie a gem mint original (common from the set) to scan and then program into the computer. The dimensions/centering should always be the same, allowing slight size/centering differences caused by different printing techniques. The scan would look for any imperfections and/or deformities in the surface paper/chrome/plastic, again allowing for slight, allowable imperfections. Then corners. I don't agree at all that these things should be left to subjective, human factors. This isn't a game. It's a grade. It either is or it isn't.
