2015 Australia 1 kilo Silver Koala BU

---

Introduced in 2007, the Australian Koala series has captured the imagination of coin enthusiasts worldwide with its annual tributes to one of the continent's most recognizable animals. The 2015 edition is particularly striking when struck in a massive format containing one kilogram (32.15 troy ounces) of 0.999 fine silver. This substantial size allows the intricate details of the design to be fully appreciated. The obverse of the coin presents a detailed scene of a fully grown koala nestled in the branches of a tree, set against a classic Australian wilderness background. This side also features the Perth Mint's traditional 'P' mint mark alongside inscriptions indicating the year 2015, the weight of one kilo, and the 999 silver purity. On the reverse, the coin displays the portrait of Queen Elizabeth II designed by Ian Rank-Broadley. This side carries the official denomination of 30 Dollars. As a sovereign coin backed directly by the government of Australia, this impressive silver piece represents a remarkable blend of large-scale metalwork and detailed wildlife art.
