What is the value of a baseball signed by Mickey Mantle Warren Spahn Stan Musial and Brooks Robinson?
Many of the baseballs are valued in price close to $500 each. The exact amount will vary depending upon the ball's condition and how it is being displayed.
A Brooks Robinson single signed baseball is worth about $60.-$70. A Mickey Mantle single signed baseball is worth about $400.-$600. I have never come across a Mickey Mantle Brooks Robinson dual signed baseball. They would be rare but by having Brooks Robinson sign a Mickey Mantle signed baseball it will lower the value. If a Mickey Mantle Brooks Robinson dual signed baseball were to come up in auction it would most likely sell below $400…
Bowman had a contract with Mickey Mantle in 1954 and 1955 There were no Topps baseball cards made for Mickey Mantle in 1954, and 1955. Bowman had an exclusive baseball card contract with Mickey Mantle. In 1956 Topps purchased the Bowman company and ended their rivalry in the sports card market. In 1989, Topps once again began production of cards with the Bowman name. Topps did issue a Mickey Mantle card in 1956.
