Sure, it depends on condition. They often go for around $250 on eBay. I'd sell it locally though through something like Craigslist or LetGo as shipping is a killer. If in pristine condition and no screen issues. It may get more. The original box also helps.
 
It is pristine. No box as was taking up too much space in closet. Ill try craigslist
 
Locally around me I see them on Facebook Marketplace for around 200 but as soon as I see them hit 150ish I will buy two for my new 2019 iMac and set up a triple monitor setup.
