1994 Upper Deck is a 550-card was issued in two series of 280 and 270 cards, respectively. The design of 1994 Upper Deck Baseball was originally intended for 1994 SP. For 1994, the Upper Deck Baseball brand name was to have been retired with the new Collector's Choice set inheriting the "flagship set" mantle. Upper Deck eventually decided to redesign SP and resurrect the Upper Deck Baseball name giving it the layout they intended for SP.
The Hobby edition of 1994 Upper Deck was regionally distributed, with three different versions (East, Central, and West) of the Diamond Collection (Series One) and 1994 SP Previews (Series Two) inserts. (1994 SP was also to have been regionally-distributed.) Where Hobby dealers and their distributors were located dictated which inserts were available. For example, collectors in the middle of the country got packs where it was possible to pull a valuable Michael Jordan Diamond Collection insert; but collectors along the East Coast were stuck with Cliff Floyd and Lenny Dykstra. The regional distribution scheme was not popular with collectors or dealers and was discontinued after this year.
Rookie Cards include Michael Jordan (as a baseball player), Chan Ho Park, Alex Rodriguez and Billy Wagner.
Many cards have been found with a significant variation on the back. The player's name, the horizontal bar containing the biographical information and the vertical bar containing the stats header are normally printed in copper-gold color. On the variation cards, these areas are printed in silver. It is not known exactly how many of the 550 cards have silver versions, nor has any premium been established for them. Also, all of the American League Home Field Advantage subset cards (numbers 281-294) are minor uncorrected errors because the Upper Deck logos on the front are missing the year "1994".
