In my opinion, never mind that stuff, it's enough of a hassle just getting good quality pictures of the thing, figuring out exactly what it is and what a wild guess of a "fair" price would be, writing up some sort of description, dealing with questions and appointments from potential customers. It makes it not worth the time and bother unless you're pretty sure you can get a few hundred bucks for it. Modulo of course how rich or poor you are right now and how much free time you have etc.
