We have seen weirder sales for much more so yes of course it can go for $20,000+ - the only question is finding the right buyer or getting found by one - what you can do about is try and find as many potential buyers as you can and approach them either via email or calling them, but be sure that it's heard by the right person either CEO, VP or some kind of director that has some basic knowledge about domains and what are the benefits - there comes your play as well how well can you play those negotiation cards. Good luck.
