Gold is a precious versatile metal
Selling the very versatile precious metal we call gold is easy thanks to the price of gold today (over $980 an ounce), and the current shortage of it. Gold has many uses in industry and medicine, besides just being pretty to look at and wear.
Many people are selling gold for cash locally or online. If you do, you can put money in your pocket in a matter of days.
Local jewelers may want it or the local pawn shop will take it off your hands, but do not expect to get the best price. You have used gold, and it will go for scrap metal prices unless you offer it in the local paper or maybe auction it on ebay.com.
