When gold backs up an IRA, chances for depreciation are  lowered because the price of Gold will not decrease, at all. Gold is a natural product whose supply is limited. So, the demand for it increases whenever its availability or supply decreases. In addition, Gold investments doesn't depend on the American dollar. People who buy gold coins and invest in them are safe from the  effects that other investment options offer. And, a gold IRA produces higher income. A gold investment is, then, more stable  and safe than a stock or a bond investment.
