Interesting info in here. Thanks all!
I'd love to unload some of my cards from what I collected as a kid. I have a handful of pretty good ones. The 1989 Griffey Upper Deck rookie card. The 1985 Topps McGwire USA Olympic card. A bunch of late 50s/1960s cards of guys like Mays, Mantle, Ed Mathews, Killebrew, Maris, etc. Rookie cards of Bonds, Maddux, Clemens, ARod, Sandberg, Dawson, etc. etc. etc.
I really have no need or even interest in them anymore, but don't want to sell them for peanuts. Interesting to see the range on Ebay, for instance, on some of these cards. That '89 Upper Deck Griffey, for instance, ranges from $20 to the thousands. I'm not going to get thousands for it, but I'd prefer to get more than $20.
