Go to a Beckett guide and look it up.  If it is from one of the main card companies (Topps, UpperDeck, Fleer, etc) then it will be listed.\n\nCondition, year printed, and rarity are also issues.\n\nIf it is some promo like a "Mother's Cookie" card, you'll have to go to a different guide.

Mike Piazza receives literally thousands of pieces of mail in care of his team; most are autograph requests. Virtually every piece of mail sent to him c/o the team is thrown away without ever being opened. Your best shot - and it's a long shot - is to try writing him in care of his agent:\nBeverly Hills Sports Council\nAttention: Dan Lozano\n131 S Rodeo Drive \nBeverly Hills, CA 90212

Depends what kind of condition the cards are in, u might want to spend a couple bucks on a beckett's basketball monthly which can be found in any card store.  If the card is valuable enough u might send it away to be graded.
