I promise not to ask if you remember when the price of gold was fixed at $35 an ounce or when U.S. currency was tied to the gold standard (hint: The Gold Standard Act was passed on March 14, 1900, but later suspended). Things have changed drastically over the years, with gold now hovering around $1,800 per ounce. Let's turn to your jewelry box, shall we? Remember all that gold you bought in the 1980s when QVC and Home Shopping Channel were coming into their own? And when you could buy gold chains by the inch at county fairs and community swap meets?
