Did you know that you can sell your collectibles? You probably have 1000s of collectibles from when you were young and don't even realize that someone's trash can be someone else's treasure. Why not make money rather than leaving it their lying in your closest collecting dust. In this example I will use baseball cards but I will also keep adding links to thousands of other websites that accept different kind of collectibles.
