In terms of its raw materials only, what Canadian coin has the greatest value?
On May 3, 2007, the Royal Canadian Mint unveiled a Gold Maple Leaf coin with a face value of One Million Dollars, though the gold content was worth over $2 million at the time. It measures 50 cm in diameter by 3 cm thick and weighs 100 kilograms, with a purity of 99.999%. The artist is Stanley Witten. The coin is mainly a promotional product to give the mint a higher international profile. The 100-kilogram coin was conceived as a one-off showpiece to promote the mint’s new line of 99.999 per cent pure one ounce Gold Maple Leaf bullion coins but after several interested buyers came forward the mint announced it would manufacture them as ordered and sell them for between $2.5 million and $3 million. As of May 3 2007 there were five confirmed orders.
