It depends. One man's trash is another one's treasure. If it's local, 20 uv a day is 20 more potential customers for a local biz owner, target local businesses. If it's blog, depends on the number of unique articles you have written. If no unique articles, it may be worth a couple of bucks for blog farmer. If it is truly not worth anything to anybody, sell it on digitalpoint. Some people may buy it for a few bucks when they see buying a pr 1 site is relatively the same price as buying pr1 link, especially if it is in their niche. Just know who you target the site to and market it appropriately.
