If you had gold coins you could sell them at a coin shop but old gold rings and chain etc. requires a second hand dealers license to purchase. If you would like a safe place to sell old gold I would recommend a place in Penasquitos called Richard West Jewelers. I found him at a web site http://www.sellgoldsandiego.com which has directions etc. The area is an upscale neighborhood in a shopping center which I would consider a safe area. They were very nice and as far as I could tell paid a very fair price for my old wedding ring. I would recommend them.
