The "Basketball Bible"
Selling price: $4.3 million
Do you know how often historians argue about the origins of baseball? All the time? Who wrote up the rules? We don't know. Where was the first game played? There's still no consensus. Recently, there's a school of thought that says the nation's national pastime didn't even start in this nation, but in England. Blasphemy!
Basketball doesn't have these issues. Dr. James Naismith came up with the rules in 1891 and played the first game in Springfield, Mass. How do we know this? Documentation, which is now owned by two rich Kansas University Jayhawks fans. David and Suzanne Booth took Naismith's two 10-by-8-inch pages of "The Founding Rules Of Basket Ball" home from a Sotheby's auction in 2010 with the tape marks from Naismith's original preservation efforts still attached. The 13 original rules were so coveted that they outsold Robert Kennedy's copy of the Emancipation Proclamation ($3.8 million) at the same event.
