A hat belonging to Napoleon Bonaparte, when he ruled the French empire in the 19th Century, has been sold for €1.9 million at auction in Paris, BBC News reported. The bicorn black beaver felt hat was valued between €600,000 and €800,000. The person who bought the hat has not made themselves known. Napoleon Bonaparte owned about 120 bicorn hats over the years. However only 20 are thought to remain—many in private collections. The hat is being sold along with other Napoleonic memorabilia assembled by an industrialist who died last year.
