Most expensive hat sold at auction

The most expensive hat sold at auction is a black felt bicorn hat that belonged to the French emperor Napoleon Bonaparte (1769–1821). It sold for €1,932,000 (£1,687,119; $2,114,284) including premium at the Osenat auction house in Fontainebleau, France, on 19 November 2023.

The hat, which was estimated to sell at €600,000-800,000, was last owned by businessman Jean-Louis Noisiez, who died in 2022, and has now been purchased by an anonymous buyer. The final hammer price was likely higher than expected as a result of the pending release of a biopic film about the French emperor, directed by Ridley Scott, premiering in November 2023.

According to Osenat, the former French emperor owned 120 hats, yet only about 16 are known to still exist today. This particular bicorn was used by Bonaparte in the middle of the Empire, around the 1806–15 period.

Previously, the most expensive hat sold at auction was another formerly owned by Napoleon. It sold for €1,884,000 (£1,498,496; $2,348,594) on 15 November 2014, also at the Osenat auction house. It was sold by the Grimaldi family, the rulers of the Principality of Monaco, and purchased by an anonymous collector from South Korea.
