Probably depends on where you're located - I'd do a quick search on Craigslist or Facebook Marketplace to see what others are asking. My best guess based on where I live (Minnesota) and what I've seen over the past 6 months (I've been looking almost daily) it would sell quickly at $400 if it is as nice as it sounds. Up to $500 if you found the right buyer.
Post a picture and others will probably chime in.
