Yep, everyone saves their cards now because they saw the value that cards from the 50s and 60s brought. But there are so many cards still out there from the 80s til now that there aren't too many rare cards worth hundreds or thousands of dollars. I have around 20,000 cards and a few hundred un-opened Starting Lineups still because I was told when I was a kid that they would be worth so much money when I got older - Parents are full of shit LOL.
Just to mention another good magazine to get values is Tough Stuff - it has a more sports in it...all bball, football, baseball, hockey, racing, figurines, and some memoribilia. Beckett used to only have baseball cards but I don't know if that has changed.
