Well if they are intentionally different cards, even with the same number, I would say they should count. I guess it's all a matter of personal opinion. For example, if I were putting together a T206 set I would consider the Demmitt and O'hara St. Louis/New York cards separate because they were intentionally updated to reflect the new teams as opposed to cards like the Magie and Doyle, NY Natl cards that were print errors and later corrected. At least the only real rule about collecting is to collect what you like, so if you like what you are doing, you are all good!
