All The Gold In Fort Knox

How many times have we heard the phrase "all the gold in Fort Knox"? While the adage about the United States Bullion Depository is probably true, there are some who think that Ft. Knox might actually be empty. Though it is widely believed that Knox holds about 3% of every refined piece of gold to have ever been made, there has not been a comprehensive audit of the facility's wealth since 1953. So, no one really knows if all the shiny bars in there are real gold or just lead and paint.
