Lead is far more abundant. Poor bloody Romans, they made water pipes and containers out of the stuff, slowly killing themselves. If we got every piece of gold ever mined that exists today, and put it all in one pile, it would fill 3.3 swimming pools. World-wide production is about 50 million troy ounces a year. A troy ounce is about 31 grams. 32 Troy ounces make one Kilogram.

Figuring out the total amount of gold that has been produced by man is a little harder. To get at some kind of estimate, let's figure that the world has been producing gold at 50 million ounces a year for 200 years. That number is probably a little high, but when you figure that the Aztecs and the Egyptians produced a fair amount of gold for a long time, it's probably not too far off. Fifty million ounces * 200 years = 10 billion ounces. Ten billion ounces of gold would fit into a cube roughly 25 meters (about 82 feet) on a side. Consider that the Washington Monument measures 55 feet by 55 feet at its base and is 555 feet tall (17 x 17 x 170 m). That means that if you could somehow gather every scrap of gold that man has ever mined into one place, you could only build about one-third of the Washington Monument.
