What is the value of a 1920s Cogswell upholstered armchair?

I have no clue but I know I own one - One from England from a dear old friend - It was in bad shape when we got it and we paid almost $500 to repair and recover it but that was almost 20 years ago - And if someone sat in it 10 times since then, I'd be surprised, it was in a formal living room - that was never used. Did you find out anything about value? I would love to know!
