At one time, this was the most valuable card in the 1991 Red Sox team set. Phil Plantier enjoyed a massive hobby following in 1991. Plantier was a highly-touted outfield prospect. He had a brief call-up in 1990, but it was not until the 1991 season that Plantier began to get the hobby following that made his cards so valuable. His Upper Deck and Stadium Club cards were his most highly-desired.
Plantier was called up in June 1991 and made a big impact. Playing mostly right field and left field, Plantier hit .331/.420/.615 with 11 home runs and 35 RBIs in just 53 games. His performance had him expected to be a big part of the Red Sox team in 1992. Unfortunately it did not really work out for him. Plantier struggled a bit in 1992 and was not the player he was expected to be. Boston then traded him to San Diego for Jose Melendez, a trade that did not work out for Boston as Plantier hit 34 home runs. But he quickly declined after that.
