BobWhenever I list a card for sale on ebay I always make it a practice to have a scan of both front and back of the card. That said I think that a seller selling a PSA 6 slabbed card has no duty, per se, to show a back scan. I have been burned before on back damage on graded cards with no back scans so I make a point to ask for a back scan or at least have the seller reveal if there is any staining, writing or paper loss and then keep the email until I receive the card and can check. I have learned the hard way.
It seems like more and more PSA 5s and 6s and SGC 50s and 40s are popping up with paper damage/loss on the back. PSA I expect, but I was surprised to see some SGC cards with paper loss in these grades as the cards I have submitted, no matter how nice the fronts, plunge down to 20 with even slight back damage as have the cards of others who have posted here on this board.
