1991 Upper Deck Baseball Final Edition Factory Set

1991 Upper Deck Final Edition is a 100-card update set. In lieu of releasing the Hi-Series set as its own factory set, for 1991 Upper Deck released a distinct "update" style set -- not unlike Topps Traded, Fleer Update, Score Rookie/Traded. This would be the only year Upper Deck would produce a Final Edition set and was packaged in the same type of box as the 1989 and 1990 Hi-Series factory sets.

In addition to the usual late season traded and impact rookie cards (#22F-#78F), the set includes two special subsets: Diamond Skills cards (#1F-#21F), depicting the best Minor League prospects, and All-Star cards (#80F-#99F). Six assorted team logo hologram cards were issued with each set. The cards are sequentially-numbered on the back with an "F" suffix.

The set contains the only "true" rookie card of Pedro Martinez and one of only two RCs of Jim Thome.
