A pair of shoes believed to be Marie Antoinette's were expected to auction for about $6,500—but they brought in $57,000, AFP reports. The white silk mules, which feature tricolor ribbons, were sold at an auction of French Revolution artifacts in Toulon, France. The queen may have worn them at a national festival on July 14, 1790, auctioneers said. (More Marie Antoinette stories.)
