Give it a good scrub, and I think you can get $200 for it in your area. I'm near Chicago, and have been looking for a vintage 900-series Trek lately (preferably lugged and rigid), and nice specimens have been priced anywhere from $175-400 and don't seem to last very long. Just a few years ago you probably would have been lucky to get $75, but between the COVID-induced bike shortage and a resurgence of retro-styled do-it-all bikes (see Crust bikes), they've been selling like hotcakes. Yours looks like it's in great condition and it's in probably the most popular size. Heck, if it had a rigid fork I'd probably give you $200 for it.
