The value of autographs signed by the New York Yankees depends on the player, the object signed, and the condition of the object signed. Players with a higher profile, or who have greater mystique in the Yankee pantheon, have signatures that carry greater interest. If collecting autographs, it is best to have the signatures in an autograph book, on a letter or a piece of paper. Signatures on equipment or programs do well also, especially if the equipment has some direct connection to the player. It is not recommended that baseball cards be signed, as that tends to devalue both the card and the signature.
