Australia 1 oz Platinum Koala BU (Random Year)

---

Introduced in 1988, the Australian Platinum Koala series represents a remarkable achievement in precious metal minting. Struck in one troy ounce of highly pure 0.9995 fine platinum, these legal tender coins carry a face value of 100 Dollars and are fully backed by the Australian government. The obverse of each coin displays the right-facing profile of Queen Elizabeth II alongside the denomination and the year of issue. On the reverse, the coin features a detailed depiction of a koala, accompanied by inscriptions indicating the weight and purity of the metal. What makes this series particularly captivating is its evolving artistry. The reverse design of the koala was changed annually, offering a fresh, unique perspective of the native marsupial with every release. Although these Australian platinum coins have not been minted on a regular basis since 2010, they remain a celebrated subject of study for those fascinated by world coinage and artistic metalwork.
