The Base Set of 2000 Revolution is made up of 150 cards, with a number of short printed rookie/prospect cards sprinkled throughout the set. These short prints are not serial numbered and were inserted at a rate of 1:4 packs. The set is organized by team and there are no subsets. There was one UER in the set, 69 Johnny Damon. By accident, Pacific has Carlos Beltran pictured instead of Damon. In fact it is the same photo as card #68.
