Obverse: The obverse features a portrait of Queen Elizabeth II (in Australia, the constitutional monarchy is in place, meaning Her Majesty Queen Elizabeth II is also the Queen of Australia). Surrounding her are the words ELIZABETH II and the country name AUSTRALIA, with the denomination 1 DOLLAR engraved at the bottom of the coin. Below the portrait is the designer’s initials IRB (Ian Rank-Broadley).
Reverse: The reverse shows one of Australia’s symbols – a koala embracing a tree, with the words AUSTRALIAN KOALA engraved above. At the bottom of the coin, the year of issue, the weight, and the silver purity are inscribed: 1 oz 999 SILVER.
About the coin: These Australian Koala coins started being minted in 2007. Each year, only 300,000 1-ounce coins are minted, making them rare and highly desirable among collectors.
