Rare Fisher KS-1 Heritage Series Speakers

I have a pair of Fisher KS-1 Heritage Series speakers in mint condition. Does anyone know how rare they are? My audio tech tells me you cannot find them anywhere......
They are worthless as speakers....so I suppose you are asking about antique value? They are very rare.
Thanks for responding.....I actually have the complete set in mint condition...including the Fisher X100B amplifier and R200 Tuner and the boxes they came in. The tuner and amp work perfectly and produce beautiful sound with my Altec Lansings.....I am intrigued by the possibilty of "antique" valuation.
