One of the biggest questions over the past 50 years is whether the gold at Fort Knox, Kentucky is really there, or if it's been plundered. What we do know is that the last 'audit' of America's gold stash was conducted on Sept. 23, 1974, when the US Treasury opened just one of its 15 vaults at Fort Knox so politicians and reporters could swarm the site for a two-hour photo-op with roughly 6% of the alleged amount held. Adding to the complete farce, none of the bars being passed around for the cameras were matched to a serial number, assayed or tested for purity, or even verified as US holdings - as foreign countries have previously stored their gold at Fort Knox as well.
