Most cards are worth less than a quarter..... unless you have some really rare cards, they fluctuate from 0 - .50 cents usually, though 50 cents isnt that common. If you have limited edition, rookie cards, and other specially marked and numbered cards they'll be worth more... beckett is alright, you can check online for certain series of cards, I was recently looking at the 1972 summit series set worth about $250 for a few cards :-) I have 2 of the 3 cards :-( Framed n everything.. i aint fuckin with no bends or creases.

Check the net first.. then go to like a card store or comic store and ask for one.
