Have you checked Ebay to see what other antique hats are selling and who is buying them? There are also a number of other auction sites you can check and use to see how other people are selling, and what they are asking, for their hats.
Do you live close to a museum, university or theater company? Sometimes those organizations will buy old hats for their productions.
Vintage stores and antique stores sometimes also purchase hats or offer consignment sales, where they take a percentage of the final sale price.
If you decide to sell online, take good, clear pictures; have thorough descriptions, even a little history if you know anything about the hat, including who wore it.
If you have a picture of a relative, or someone wearing it, that adds value so I would include a copy of the photo.
