The biggest, heaviest, inherently the most valuable gold bullion coin in the world has been unveiled by The Perth Mint.

Weighing a massive one tonne of 99.99% pure gold, the monumental gold bullion coin measures nearly 80cms wide and more than 12cms deep. This stunning gold coin is the pinnacle of ingenuity and innovation for which The Perth Mint is renowned. Chief Executive Officer, Ed Harbuz, reveals that the Mint’s dedicated team of talented artists and technical staff worked tirelessly for months to create a gold coin of this magnitude. “To cast and handcraft a coin of this size and weight was an incredible challenge, one which few other mints would not even consider,” he said.

As the showpiece of the Australian Kangaroo Gold Bullion Coin Program, its classic design by Dr Stuart Devlin AO CMG, goldsmith and jeweller to Her Majesty Queen Elizabeth II, has featured on each annual 1 kilo release in the series for more than 20 years. The one tonne gold masterpiece features a bounding red kangaroo surrounded by stylised rays of sunlight and bordered by the inscription AUSTRALIAN KANGAROO 1 TONNE 9999 GOLD and the year-date 2012.

Issued as Australian legal tender, the obverse of the gold bullion coin features the Ian Rank-Broadley effigy of Her Majesty Queen Elizabeth II, accompanied by the inscriptions ELIZABETH II, AUSTRALIA and the monetary denomination of 1 MILLION DOLLARS.

The popular Australian Kangaroo Gold Bullion Coin Program offers a stunning choice of gold bullion coins in a range of sizes, with various mintage limits and annual design changes.

While the design of the 2012 1 kilo release will mirror its super-sized companion, the 1/10oz, 1/4oz, 1/2oz and 1oz coins will feature a standing kangaroo set against an outback scene.

The weight and purity of each issue is guaranteed by the Government of Western Australia making Australian Kangaroo coins a secure way to diversify any investment portfolio.
