The "U" that precedes the number stands for Update on cards from the Fleer Update set. For example U25 would be the 25th card of the Update set. Traded or Update Sets are a set of cards, usually factory packaged, that features players who switched teams during the season, as well as those who made their debuts. Topps, who started this trend in 1981, is most well known for traded sets. Other companies also produce traded sets, although they refer to them by different names such as "Update" (Fleer) and "Rookie/Traded" (Score) sets.
