I don't see the staple cards like the Bowman Pujols and Trout signed rookies going down at all. They've only gone up. Modern collectors, as long as they're around, will always chase those cards. I can see the Trout card, when all is said and done, being looked at like the 1952 Mantle.

People chase them for the same reason they did the 89 UD Griffey. They're iconic cards of iconic players. Lesser cards will fluctuate, but the Griffey still goes for a pretty high price for a base set card released during the height of junk wax.
