Frayed, torn and maybe a little bloodstained, the only U.S. flag not captured or lost during George Armstrong Custer's "Last Stand" at the Battle of Little Bighorn sold for $54 when it first surfaced in the 1890s.

On Friday, the swallow-tailed 7th U.S. Cavalry standard, known as a guidon, was sold for $2.2 million at an auction at Sotheby's in New York. Also up for bids was James Naismith's original Founding Rules of Basketball, including handwritten notes by Naismith about the intricacies of the game, which sold for $4.3 million, Bloomberg reports.
