Lol. I make most of my money (from domains) selling domains for around 15 a piece, but I understand what you're saying.
It is POSSIBLE that you could get more, even considerably more, but there are literally millions of pretty good domains for sale and you have to be pretty good at marketing them or lucky to get a high sale price for an undeveloped domain... well, most of the time, anyway... I mean, if you happened to have hosting.com or something, you could pretty well plan on getting a good price...
Best wishes,
Richard.
