Well, it's always worth more if you're selling than if you're buying
It's kind of a niche machine and probably has a somewhat smaller market. What it's worth to others would just be a guess on my part but if I were looking for one I would expect to offer somewhere between $250 and $400 in the condition you described. If it was really special, I've seen them listed as high as $600 but that is not the norm. There's few, if any repro parts so some replacement stuff could be harder to come by than the high volume brands.
My neighbor bought a brand new one in the early 70s. The powder blue and eggshell white paint scheme didn't exactly scream domination but it did have some red so maybe that made it look more aggressive. It did have a certain appeal though and was rock-solid from a mechanical point of view. He and his wife rode it as a 2-up, which was pretty common back then.
