I came across a Fisher Custom Electra VI Console (1963) Model E-48 in walnut in really nice shape (aesthetically clean). It isn't currently working (as it produces a very loud tone when turned on).
A variation of this question was asked a month ago.
Most of these "middling" Fisher tube consoles can range as high as $600 or more if perfect cosmetically and functional electronically.
If the cosmetics are lovely but the electronics are suspect, you are talking a minimum of $100 to $150. Depending upon the local market the value, even needing an electronic refurb (but assuming the iron and most of the tubes are good), is as high as $350 to $400.
