It is a printing error caused by the printer flipping the sheet the wrong way before printing the second side to be printed. I have and have seen many cards from many different issues where the printer made this kind of error. They usually end up with an offcentered back because the cards were aligned for cutting with respect to the fronts, not the backs. It would command a very decent price from specialty collectors who like print error cards.
