The World Gold Council estimates that all the gold ever mined, and that is accounted for, totals 187,200 tonnes, as of 2017 [3] but other independent estimates vary by as much as 20%. [4] At a price of US$1,250 per troy ounce, marked on 16 August 2017, one tonne of gold has a value of approximately US$40.2 million. The total value of all gold ...

Immediately following passage of the Act, the President revalued the price of gold to $35 per troy ounce. This devaluation of the dollar drastically increased the growth rate of the Gross National Product (GNP) from 1933 to 1941. Between 1933 and 1937 the GNP in the United States grew at an average rate of over 8 percent. [4]

For example, if one owns a share in a gold mine where the costs of production are US$300 per troy ounce ($9.6 per gram) and the price of gold is $600 per troy ounce ($19/g), the mine's profit margin will be $300. A 10% increase in the gold price to $660 per troy ounce ($21/g) will push that margin up to $360, which represents a 20% increase in ...
