Reply #27: It depends on what you are selling to some extent. If you have something that is rare it will sell.

I've sold model trains. You get a feeling for what people really want. Mostly it is things that are good quality but are no longer produced. I bought a model train kit last week for $37 plus shipping and I know I can resell it on ebay for $100 or more. The listing I bought it from was not the listing that most people would go to, to find it. The seller did not know the worth of the item to people in the hobby. I'm going to resell it as soon as it arrives. I'll probably make about $70 off it.
