1989 Australia 1/2 oz Proof Platinum Koala

---

In 1989, the Perth Mint in Australia struck a remarkable platinum coin that captures the unique natural heritage of the continent. This half-ounce piece is composed of 0.9995 fine platinum and carries a legal tender face value of 50 Dollars, fully backed by the Australian government. Known for its limited production, only 2,400 of these proof-quality coins were minted, making them a scarce find for enthusiasts of fine metalwork. The obverse of the coin displays a right-facing portrait of Queen Elizabeth II, surrounded by the inscriptions indicating her name, the country of origin, and the fifty-dollar denomination. This classic royal likeness establishes the official, sovereign status of the coin. On the reverse, the coin features Australia's beloved marsupial, the koala. A key characteristic of this particular numismatic series is that the Perth Mint alters the koala imagery for every year of issue, ensuring that the 1989 design remains entirely distinct. The reverse is also inscribed with the year 1989, the name of the series, and details confirming the half-ounce weight and 9995 platinum purity.
