Here is the Mariano Rivera rookie card by Bowman, 1992. Yeah, I know not very exciting, Mariano in his street duds. However, Mariano is considered to be the greatest baseball closer of all time. This baseball card is valued at $100 and up.
Mariano Rivera is now truly the greatest closer of all time. He just got his 602 save, most of all closers. He is a 12x all star and has helped the Yankees win the World Series 5 times. He is the all time leader in postseason saves, with 42. When Rivera enters the mound at Yankee Stadium, he does so to the strains of Metallica’s ‘Enter Sandman’.
