The most expensive weapon sold at auction is a sword used by the French Emperor Napoléon Bonaparte (1769-1821), which achieved a record price of €4.8 million (£3.3 million; $6.5 million), when it was sold by one of the Emperor's descendants to another branch of descendants, during an auction in Fontainebleau, France, on 10 June 2007. The 100-cm (39-in) curved steel blade is decorated in gold, with an ebony and gold handle and protected by a gold-decorated sheath; it is believed that Napoléon carried the sword into the Battle of Marengo, Italy, in June 1800.
