1988 Australia 1 oz Platinum Koala BU (Inaugural Issue)

---

In 1988, Australia introduced a brand new platinum coin series that captured the attention of the global numismatic community. This inaugural release features one troy ounce of highly pure 0.9995 fine platinum, representing the very beginning of a celebrated annual tradition from the historic Perth Mint, an institution that has been operating since 1899. The reverse of this initial issue showcases a detailed depiction of a koala looking directly forward, rather than the profile views often seen in wildlife coinage. This distinctive design choice highlights the soft features of the iconic Australian marsupial. Backed fully by the Australian government, this sovereign coin carries a legal tender face value of 100 Dollars. The obverse side displays the right-facing profile of Queen Elizabeth II. Surrounding her portrait are the inscriptions confirming her name, the issuing nation of Australia, the year 1988, and the denomination of 100 Dollars. With a recorded mintage of 61,682 pieces, this brilliant uncirculated coin stands as a significant milestone in modern minting history.
