Since its debut issue in January 1989, SI for Kids has included a perforated sheet of nine standard-size cards bound into each magazine. In January 2001, for the second time, the card numbers started over at 1. Listed below are the cards issued in magazines that carry 2003 cover dates. The athletes featured represent an extremely wide spectrum of sports. Although originally distributed in sheet form, the cards are frequently traded as singles. Thus, they are priced individually. The value of an intact sheet is equal to the sum of the nine cards plus a premium of up to 20 percent.
