1. How much gold is there?

In the world there are currently somewhere between 120,000 and 140,000 tons of gold ‘above ground’. To visualize this imagine a single solid gold cube with edges of about 19 meters (about three meters short of the length of a tennis court). That's all that has ever been produced.

 

Divided amongst the population of the world there are about 23 grams per person, about 1.2 cubic centimeters each. This equates to about $250 - $350 worth per person on Earth, depending on the current price.
