What is the value of a Brooks Robinson and Mickey Mantle autographed baseball?

Answer 1

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.

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 are not properly authenticated could sell at half the market value or less.

Answer 2

A Gaylord Perry single signed baseball is worth about $50.-$100.

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. Add for inscriptions. Collectors will pay more for inscriptions like "HOF 91" and pay less for personal inscriptions like "Good Luck Chuck." In a recent auction (Nov. 2008) a Gaylord Perry single signed baseball sold for $71.70 .
