Most Expensive Bladed Weapon: Napoleon Bonaparte’s Marengo Cavalry Saber

Price: $6,500,000

The most expensive antique weapon to have ever sold at auction is a gold encrusted sword used by Napoleon Bonaparte in battle around 200 years ago. The 32-inch sword brought 4.8m ($6.5m) against a 1.2m pre-sale estimate at an Osenat auction in Fontainebleau, France in 2007. Napoleon used the sword at the Battle of Marengo in 1800 to take control of northern Italy from Austria.
