As Topps and Bowman vied for baseball card supremacy in 1955, each side signed a number of raw rookies and "bonus baby" youngsters who teams had to keep on their MLB rosters for multiple years, whether or not they planned to use them. Sandy Koufax became perhaps the best of those signings, for Topps itself as well as the Dodgers. This two-pose card accentuates Sandy's youth and his need for patience, as it would take several seasons for Koufax to blossom into baseball's top lefty.

This PSA PR 1 grade reflects modest creasing, rounded corners, and some foxing on the reverse. His rookie card remains one of the key additions to any 1955 set or Hall of Fame collection and this presents an accessible way to get one. Just remember to take its back cartoon about Cooperstown with a grain of salt.
