Items listed in the Classified need to have a price attached. I cannot see on the sweat band where it states it is 100% beaver content. Can you snap a picture of that and post?
John Lofgren Monkey Boots Shinki Horsebuttt - $1,136 The classic monkey boot silhouette in an incredibly rich Shinki russet horse leather. 
Grant Stone Diesel Boot Dark Olive Chromexcel - $395 Goodyear welted, Horween Chromexcel, classic good looks. 
Schott 568 Vandals Jacket - $1,250 The classic Perfecto motorcycle jacket, in a very special limited-edition Schott double rider style.
Check the Classified ads here to get an idea. Use the Google search "Fedora Lounge, Borsalino" or check the history of Borsa sales on Ebay. This will give you a range. Without it stating its beaver content the provenance/quality of the hat could be suspect. Or attach a price and see if there is any interest at that price.
Do some research, and your price will be then based on actuals. You increase your chances of selling if the price reflects the market. Sometimes selling things requires a little bit of work on the part of the seller. But $400 is a start and now you can gauge the response.
