Wait, is this the "thread about nothing"??
If I wanted to be serious, which I only do on Mondays usually, I'd say you either get cheaper , low grade copies of the cards you like looking at the best ...or take a chance on higher value cards. I don't keep cards out anymore, since my office is too sunny and I don't want them to get faded. I also don't keep my truly valuable cards in the oven, but that's just me...
