Mickey Mantle – 1951 Bowman
This list includes Mickey Mantle twice. Despite the fact that the 951 Bowman is less valuable than his Topps rookie card, it is still his only official rookie card. Among the baby boomer generation, the value of a perfectly preserved credit card can be as high as $500,000.
Eddie Plank – 1909 T209
Eddie Plank’s T209 version is one of the most highly rated and sought-after cards in the deck. Many have speculated as to why this card is so valuable, with the most common answer being that it is extremely rare. At the time, a large number of automobiles were ruined by the printing plate.
