The money in circulation today ($USA) is 1,18 trillion dolars (data 20.03.2013, Federal Reserve). Gold minted during our presence here is now 171,300 metric tons. Therefore there's $6,888.5 per kilo of gold. The current (27.03.2013) gold value per kilo is $51,267 (http://goldprice.org/) which means this is overpriced about a factor of circa 7.5. That's because NOT ALL of gold is available for trading.
