Technology
Isn't there some kind of technology that the graders could use to put on every card they grade like a microscopic scan or trace that would leave an indelible electronic footprint of the history of the card? PSA receives a raw card and first thing they do is scan it. And something on the magic wand reads "PSA 6 - 12/12/15."
To work would have to be an industry thing of course. While this would influence their expertise and judgment, being what it is, at least it would tell them the formal grading history of the card and may raise flags on alteration.
Does such super high powered technology exist. I haven't a clue. In this day and age seems like it should.
