What is the value of a Sandy Koufax and Don Drysdale autographed baseball?

Answer 1

The value of a multi signed Baseball cannot be priced by the value of each signature added up. Multi signed baseballs are valued as a group of signatures, and how desired that group is as a whole. This does not necessarily mean that two signatures will sell for less than one, but in most cases it does, or at least not the full value of the two signatures added up. A Sandy Koufax single signed baseball is worth about $250. -$400., a Don Drysdale single signed baseball is worth about $150. -$200. A desired pair of signatures, a Sandy Koufax Don Drysdale dual signed baseball is worth about $300.-$400. Value is based on average prices of recently closed auctions. Prices may vary based on condition, and the type of authenticity that accompanies the baseball. Signatures that have not been properly authenticated could sell at half the market value or less. In a 20008 auction a Sandy Koufax Don Drysdale dual signed baseball sold for $358.50
