Right Sunnybank. The 15/1 ratio has been out of whack for quite a long time now. Under that historic valuation, $1500 an ounce gold would translate to 100 dollar silver. In Roman times, the price ratio was set at 12 or 12.5 to 1. In 1792, the gold/silver price ratio was fixed by law in the United States at 15:1, (by Secretary of Treasury Alexander Hamilton) which meant that one troy ounce of gold was worth 15 troy ounces of silver; a ratio of 15.5:1
