I suggest searching for sold listings here and on QRZ.com. It was an amazing rig in its time, but the demand for the older rigs seems to have declined in value because of the IC-7300 and the difficulty getting repair parts. Without a tuner, it would seem to be a starter radio , or a receiver for an SWL. I tried hard to get $450 for my very good condx "5" serial number, fully filtered TS-850/AT with new capacitors at several flea markets, but no takers. Though I admit the audience at flea markets is smaller than eHam. I finally settled for $375. But that's just one data point.
Suggest that you advertise it for what you would like to get and see if you get any takers. You can always drop the price.
You may find a collector who really wants one.
