How much gold is at Fort Knox?

For nearly 80 years, a very large portion of America's gold has been held in reserve at the U.S. Bullion Depository, known more commonly as Fort Knox. And even though we switched off the gold standard in 1971, the idea that billions of dollars worth of gold bars are just sitting in Fort Knox gathering dust, is a tantalizing fantasy for any criminal mastermind. But exactly how much gold is kept at Fort Knox? The amount of gold held at Fort Knox has fluctuated over the years. It was at its greatest amount during World War II when several European governments moved their gold reserves to Kentucky for safe keeping. At this time, the amount of gold at Fort Knox peaked at 20,205 metric tons (650 million oz. troy). Also during WW2, the original copies of the Declaration of Independence and the US Constitution were moved to Fort Knox as were the Hungarian Crown Jewels and a copy of the Magna Carta. Currently, the vault holds 4,578 metric tons of 368,000 standard, 400 oz. troy gold bars. That's equal to three percent of all the gold that has ever been found and refined in human history. Fort Knox holds roughly $180 billion worth of gold.
