One autographed baseball just sold for $600,000+
It is signed by Babe Ruth, Ty Cobb, Honus Wagner, Walter Johnson and many others.
As of the signing date, which marked the June, 1939 opening of the Hall of Fame building in Cooperstown, there had been just 12 players voted into the Hall of Fame. Ten of them were still alive at the time, and all ten signed the ball. (Christy Mathewson and Wee Willie Keeler were absent because they had passed away quite young, aged 45 and 50 respectively.)
