Al C.risafulliTake a good look at the card first - I read somewhere it's actually the ink from the front of the card showing through to the back, as opposed to the kind of sheet transfer issues you see with T206 that creates a ghost image on the back of the card. It's very common with '33 Goudeys and I see it a lot with rich reds and deep blues. I've never heard of a premium assigned to such cards.
