Response to Question: 2001 UD Johan Santana "Star Rookie"
Thanks for the question. This card only books for $5 because, although it says "Star Rookie" on it, 2001 wasn't actually his RC card year (it's 2000). If the card was from the 2000 UD set, it probably would book for $15. I would understand it saying "Star Rookie" if 2001 was his debut season in the majors, but he actually debuted in 2000. Maybe because it's Upper Deck's first card of Santana. Anyway, that's the reason for it's current book value. $5 actually isn't that bad for a 2nd year card of a player that Beckett considers a "Semistar", although we all know Santana is one of the best pitchers in the league.
Thanks for reading!
