As a stunt to publicise the 99.999% pure one-ounce Canadian Gold Maple Leaf series, in 2007 the Royal Canadian Mint made a 100 kg 99.999% gold coin, with a face value of $1 million, and now manufactures them to order, but at a substantial premium over the market value of the gold. [3] [4]
Example calculation assumes for simplicity that the only valuable material on asteroids is platinum. On August 16, 2016, platinum was valued at $1157 per ounce or $37,000 per kilogram. At a price of $1,340, for a 10% return on investment, 173,400 kg (5,575,000 ozt) of platinum would have to be extracted for every 1,155,000 tons of asteroid ore.
