G. H. Heinemann Manufacturing Co.

I recently purchased a hat at an estate sale. It is a derby style hat. The label says Heinemann Manufacturing Co. It also has a United Hatters sticker under the leather interior band. The leather band is tooled with the Name: The Badger Hat. I found that the hat name was registered in August 1903 by G.H. Heinemann & Co. Milwaukee Wisconsin. When the company owner retired in 1904, his son, James took over management and incorporated the business on Nov.8, 1904.
My dilemma, I have not seen any examples of the hat on the internet. I'm hoping some one here would know if it's rare or of any special value. I'd like to know if I got a good deal. Thanks in advance for your responses.......Al C.
