Many possible uses-- one might be for a site specializing in one-word dot-coms. If I had to hazard a guess, $200-$400 to just the right buyer, $40 or $50 wholesale on ebay. Would be super if you had the plural too. Easy to say and spell.
Too many similar creative/made up type domain around which never sell. If people wanted a name like like they would simply think up something similar and register it themselves.
