National Geographic goes to 33 Liberty Street in New York City to visit the Federal Reserve’s gold vault, home to about one-quarter of the world’s gold. Beginning at about the 3 minute mark, you get to see what one tonne of gold looks like, another reminder of just how dense the metal is.
About half-way through this segment, they visit the New York gold district and then they begin a discussion of the current monetary system with this:

In part two, they go to Washington to visit Fed Chief Ben Bernanke. Pretty interesting stuff.
