I own t206 cards and don't have a problem with them, but sometimes their prices are quite disproportionate to the rest of the hobby.
I have shown and seen cards shown where someone has the response along the lines of "Man, if that was a t206 you could retire".
So I would like to see these cards.
Misprints, Miscuts, Rare Backs, HOFer with less quantities known than it's t206 counterpart.
HOF with two backs and another player name on top (Ford).
Misaligned front registration, along with a double printed back
I have more, but I will stick to these for now and allow more to be shown.
