Cocked hats such as Napoleon’s (or Nelson’s) were made of felt. Good-quality felt in Napoleon’s time was made of beaver fur, which has the advantage that the individual hairs have microscopic barbs on them, which mean that they can easily be matted into a durable lustrous felt. Cheap hatting felt was (and still is) made from rabbit fur, which has no such barbs and needs chemical treatment to make it felt. In the 18th and 19th centuries the chemical used was mercury, which gave very many hatters chronic mercury poisoning; the symptoms include inflammation of the mouth and lips, muscle tremors, and mental and behavioural changes. This syndrome was so common in the trade that it was known as ‘hatter’s shakes’, and may be the inspiration for the character of the Mad Hatter in Alice in Wonderland.

Initially, the price of the hat was 48 francs, but then Poupart raised it to 60 francs. Every year, the Imperial Costume Department purchased four pieces, the service life of which was three years. Napoleon had a very sensitive head, so the hat was stretched a little before being worn. The size of the hat varied from 44 to 47 centimeters in length and 24 to 26 centimeters in height. In total, he had about fifty hats, some of which were lost in battles. During his last exile to Saint Helena, he took four hats with him. And recently a man bought one of his hats for $1.4 million here is an article by Bryan Goldberg Napoleon Hat, I was a little shocked actually.
