Just for the sake of clarity, what makes this as simple as a print error, and what makes the 1990 NNOF Thomas RC a highly prized error card? Aren't they for all intents and purposes the same error? Pretty sweet IMO man. I would sell them if I thought they would bring a premium, although I wouldn't put anything misleading in the auction.
