I hate to bring up this question and sound like some sort of conspiracy theorist, but is it possible that someone could take a group of E104 blank backs (whose fronts are identical to the corresponding T208s), and have the backs printed in T208 fashion?
If this were so, would PSA or SGC be able to catch it?
And to answer any questions, no, I haven't tried to do this, nor do I want to. E104/D359/T208 cards are too expensive for my sardine-sized budget.

I'm just wondering if this "flood" of T208s suddenly hitting the market might portend some hidden motives/shenanigans.
