History
Australian Kangaroo
Kangaroos are only found in Australia, these unique animals have gait and movement unlike any other animal in the world. The red kangaroo, depicted on Perth Mint's coins and bars, is the largest of all kangaroos, the largest terrestrial mammal native to Australia, and the largest extant marsupial. They hop across Australia on large, powerful legs, and use an oversized, muscular tail to help balance their bodies. They are found across mainland Australia, avoiding only the more fertile areas in the south, the east coast, and the northern rainforests.
Kangaroos were first depicted on the coin in 1989 when the Perth Mint released their Gold Nugget coin in new design and changed its name to Kangaroo. Besides being depicted on the Australian Kangaroo coins and bars, the kangaroo appears as an emblem on Australia’s coats of arms.
Minted bars refer to the manufacturing process that is applied to create them. The process begins by heating gold material in a furnace until it turns to a molten slurry. During the heating process, all unwanted impurities in the slurry are removed until only molten gold of high purity is left, most often at around 99.99%. The molten gold is then poured into moulds, usually in the shape of large bars, where it cools and solidifies. The solid gold is then inserted into a mill that rolls the gold into panels with a uniform dimension. Afterwards, the gold panels are inserted into a blanking press that punches blanks out of the gold panels. The next step involves the weighing of each gold blank to ensure that it is neither underweight nor overweight and those that pass this test are then polished for them to obtain a shiny surface. The last stage involves the minting process where the gold blank is inserted into a minting press that presses its die with huge force to transfer the design from the die onto the gold blank. The result is a minted bar. The newly minted gold bar is then inspected before being sealed in a transparent tamper-proof protective package.
The Perth Mint is a world distinguished mint and precious metals refiner that is located in the City of Perth, in Western Australia. The Perth Mint was founded in 1896 by Britain’s Royal Mint in response to the newly discovered gold deposits in Western Australia. Perth Mint’s task was to refine gold ore from the mines and to strike sovereign gold coins from the refined bullion. Between 1899 and 1931 the Pert Mint produced a considerable amount of gold sovereigns which were distributed in Australia and throughout the British Empire to be used as circulating currency. British control over Perth Mint was relinquished in 1971 to the Government of Western Australia which then assumed ownership of the mint. Today, the Perth Mint is hailed for the exceptional quality of its world class investment bullion coins like the Kookaburra and Koala silver coins, and the Lunar Series. The Perth Mint has been a member of the London Gold Market (predecessor of the LBMA) since 1934. The swan design, which is the Mint’s official assay stamp registered with the LBMA, is recognised internationally and was inspired by the Mint’s location in Perth, where the main river, the Swan, runs through the city.
