The human body is composed of many elements, including Gold in trace amounts. According the technical treatise, The Elements Third Edition, written by John Emsley and published by the Clarendon Press, Oxford in 1998, the average person's body weighing 70 kilograms would contain a total mass of 0.2 milligrams of gold.
Simply so, how much is .2 milligrams of gold worth?
Well, there are 31.1 grams in a troy ounce, so we must divide 14 milligrams by 31.1 grams. A few keypunches tell us the coin is clad in 0.00045 troy ounces of gold (0.014 / 31.1 = 0.00045016). Simple: Multiply that number by gold's current price of $1,660 per ounce and you get $0.747.
