With the economy in decline, and the price of gold above $960 per ounce on February 25, demand for gold is on the rise. It's a big topic these days and one I'm focusing on more and more on Mad Money. So I’m going to spend the next few days here talking about the gold market; how to buy gold, where your best options lie, and how to avoid scams when trading in gold.

Channel 10 then sold the last ring to a San Diego pawnshop.
