unique signed chiefs hat

lordmatt

I've been holding onto a hat that I believe is one of a kind for almost 25 years, and I'm wondering what kind of value it might have. the hat in question is a chiefs hat that I had signed around 1997 at a football camp I attended, and has signatures from Neil Smith, Derrick Thomas, and Ben Roethlisberger. I don't even know where to begin when it comes to pricing sports memorabilia, and was hoping someone here could give me an idea of it's value. thank you!
