Even pristine, it's 50 years old and like Randy mentions that means it likely needs a refurbish. It does help value IMHO being as-is rather than poorly restored. Also if all the knobs, chassis, mechanicals are in good shape, this helps a lot, as would it's original tube complement.
It's not a super collectible receiver (e.g. Collins, Drake, Hallicrafters), but is highly regarded. It was a kit, which makes it desirable because I bet a lot of people had them and sold or lost them over the years. The nostalgia aspect for a nice example is good.
It covers up to 10m, which is cool and was probably pretty exciting in 1962 being a single conversion receiver. It should do the commercial AM band as well as the ham bands, so I'd bet that it would work well as a general purpose receiver. I would give it the once over and try it, personally. It's pretty amazing how good the boat anchors sound. Even very nice gear now sounds thin and tinny in comparison.
