Because of Michael Jordan’s high profile as a professional athlete, and the attention he drew, he was not a prolific signer of autographs. This has helped to drive the desirability of his autograph and any items he signed, up. When purchasing his autograph, or items that bear his signature, buy only those items that have been authenticated by a recognized agency (such as Upper Deck). This is a necessary protective measure because fake signatures have flooded the market. The value of his signature varies somewhat – an autographed piece of paper (while still quite expensive) carries less value than an autographed uniform or piece of equipment. If you possess an autograph or autographed item, visit several on-line vendors to get an idea of its value.
