What Is this Phone value? Kellog S & S chicago Ill,,made in Kansas City manufacture

I would like to know more about this phone, I think it is around the 1902 time frame, But I cannot find one like it any where. It was made by the Kansas City manufacture, it is a kellog S & S chicago Ill. It came out of a house I once owned in North Central Neb.
Can anyone tell me what it might be worth or is it worth refubishing,,without losing any Value?

Thank you
