Estate Jewelry by the ton finds it's way onto Ebay. As the Baby Boom ages there will be more and more of these old items going up for auction. It looks like a great place to find "sleepers". "Estate Jewelry" covers such a wide range of items that sellers frequently sell things about which they know nothing. If you develop a specialized knowledge about selected items you should be able to make some money by buying cheap, identifying, and re-selling with the correct description and identification.
