I saw this too and at first I thought my eye's were bugging on me - Mike Schmidt in the Pre-30's section? WTH??!
Alas, apparently this is how it's suppose to be?
My saved search of "T206" still yields correctly, but the other searches do not. I guess technically, NOW would be a good time to BUY (because who's going to go through 125K listings to find a particular card) but it's sure as heck NOT a good time to sell.
