Good post Steve. I think Bob L has removed some listings from SCD that no longer make the cut, like border gaps, but removing cards like Herrer, Bakep or the black star Campos would be hard at this point given the value attached to them in the hobby. Dick Gilkeson also did a very good publication on card variations in all sports. I think it was first published in 1988 and updated through 1995. He would publish variations/errors he had heard about but note them as unverified.

A good example of more modern cards with defects like the Herrer having a harder time gaining acceptance today are the missing "black" cards in the 1990 Topps set that are apparently related to the No Name Thomas, which is recognized and draws big bucks. The defects on the other cards from the same sheet are less recognizable and were later discoveries. I think they have now been listed in Beckett and the thread on CU about these cards and the Thomas provide an interesting look into how some of these defects may occur
