This 325-card set was distributed in two separate series. The standard hobby-only product, containing cards 1-300 of the base set, was released in late December 2001, and features a 300-card base set that was broken into tiers as follows: 200 Base Veterans, 60 Rookies/Prospects (numbered to 1350), and 40 Fan Club cards (numbered to 2025). Please note that a few of the players autographed a portion of their cards. Thus, cumulative print runs are listed in our checklist for these cards. Cards U201-U225 were distributed exclusively within hobby packs of 2002 Donruss the Rookies in mid-December, 2002. These twenty-five update cards are all serial numbered of 1,350 and feature a selection of prospects. Though odds per pack were never released by the manufacturer, we estimate the cards were seeded at a rate of 1:17. Please note, these update cards were originally intended to be numbered as 301-325 for the checklist, but were erroneously numbered 201-225. We've added a "U" prefix to the update card numbers to avoid confusion within our checklist.
