What is the value of a baseball signed by Brooks Robinson and Joe DiMaggio?
Joe DiMaggio Brooks Robinson Dual Signed BaseballA Joe DiMaggio Brooks Robinson dual signed baseball is worth about $300. -$350The value of multi signed baseballs 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.Groups of signature that are connected by a theme, such as a team, Hall of Famers, 300 win pitchers or 300 hit club or teammates will have a higher value than random signatures of players. DiMaggio and Robinson have no connection except being in the HOF, and would be less desired to collectors. The Joe DiMaggio signature would have a higher value by itself.
