It's worth as much as mynewdomainihaventregisteredyet.com. Domains are only worth something if; a) you had the domain like pepsi.com before pepsi got started and they want your domain or b) if the domain gets good traffic already and can make something in return for the purchaser.
For someone in the area of, "I'll pay for it because I like it or because it is my company name", you negotiate a price with them... Don't let them make the first offer, you want to start outrageously high and meet in the middle type of deal.
If it brings in money, you sell it for what it would make in a year and a half or so. Start at a 2.5 year value and let them talk you down some. This is a little harder because you would have to prove to them fully, that it generates a specific income on an average day. You can also add on the price of the website itself, if they want it with the domain and with this, you should use a slightly above average cost to develop a site of that magnitude.
Considering there isn't a site on your domain, you'd probably sell it to someone that likes the name... what ever it means.
