Traded most of mine to Amazon. They give you varying value based on marketability of the performer, release year, and title. They also include for the shipping back to them. So all you need to do is pack them, and drop at the post office.
You may not get top dollar, but its a lot less hassle than selling individually, and you get credit to buy more music.
