The 2012 Australian Kangaroo One Tonne Gold Coin issued by The Perth Mint has been confirmed as the largest coin in the world by Guinness World Records and will be featured in the 2013 Guinness Book of World Records available in October.

It is also the world's largest and heaviest gold bullion coin -made from 1 tonne of 99.99% pure gold.

"We faced an incredible challenge to produce a coin of this scale, so this is a wonderful endorsement of the talent and expertise of those involved," said Ed Harbuz, Perth Mint Chief Executive Officer.

Cast from 99.99 percent pure gold extracted from Australian mines, the coin weighs a total of 1,012 kilograms and measures 80 centimeters wide and 13 centimeters deep. The coin was made earlier this year in the presence of experts from the fields of metal assaying, numismatics - or coin collecting - quality assurance, and scale calibration and weighing, who verified the specifications of the coin.

Staff involved in the mammoth project, whose skills include designing, refining, assaying, casting, finishing and more, gathered together for this celebratory photo call on receipt of their official record certificate.
