About the Coin: Since 2007, the Perth Mint has introduced the "Silver Koala" coin series. Each year, a coin featuring a different image of this animal is issued. When early European settlers first encountered the koala in Australia, they believed the tree-climbing animals were monkeys or bears. Koalas are known for unique physical traits that assist their tree-dwelling lifestyle. They can grip branches and pick eucalyptus leaves, with tough skin and sharp claws providing grip while climbing. Koalas have very dense and thick fur, allowing them to comfortably sit on branches for hours. These unique Australian animals are a great icon representing Australia's fauna in the coin series.
