The biggest coin in the world was created in 2007, when the Royal Canadian Mint unveiled a monster size gold coin with a face value of $1 million Canadian dollars. This coin is said to be the biggest, purest and highest denomination coin in the world.
This giant one million dollar coin is about the size of an extra large pizza and weighs 100 kilograms or 220.5 pounds. The closest rival to the C$1 million coin of Canada is the 31-kg 'Big Phil' coin manufactured to honour the Vienna Philharmonic Orchestra with a face value of only 100,000 euros.
This one million dollar coin from Canada was produced at its Ottawa plant, where one-ounce gold bullion coins are also made. It is 53 centimetres (21 inches) in diameter and over 3 cm (1.2 inches) thick. Though the coin has a face value of C$1 million, it is worth more than twice of that because of the rising prices of gold. The new one million dollar gold coins are decorated with the Canadian maple leaf and boast 99.999 percent purity.
This biggest coin in the world was produced in a very limited quantity and has been ordered by the USA and some countries in Europe and Asia.
