1 Dollar - Elizabeth II 4th Portrait - Koala - Silver Bullion Coin

Historical Context: The 2009 Australian 1 Dollar Koala silver bullion coin features the Ian Rank-Broadley Fourth Portrait of Queen Elizabeth II, an effigy widely adopted across Commonwealth coinage from 1998. Issued by Australia, this coin is part of the Perth Mint's highly successful Koala series, which began in 2007. These annual releases are significant for their blend of intrinsic silver value and collectible appeal, reflecting a global trend in government-issued bullion coinage that commenced in the late 20th century, celebrating Australia's unique natural heritage.

Artistry: While a specific individual engraver for the Koala reverse design is not typically credited on the coin itself, the artistry emanates from the skilled design team at the Perth Mint. The obverse displays Ian Rank-Broadley's realistic and dignified portrayal of the monarch. The reverse presents a naturalistic and highly detailed depiction of a koala, a quintessential Australian marsupial. This artistic approach emphasizes realism and intricate texture, characteristic of modern bullion coin designs intended to highlight the subject's natural beauty and appeal to a broad international market.

Technical/Grading: Struck in .999 fine silver, weighing 31.1035 grams and measuring 40.6 mm, this coin exhibits excellent technical qualities typical of Perth Mint issues. Key high-points for grading include the fine details in Queen Elizabeth II's hair and crown on the obverse, and the delicate fur texture, eyes, and claws of the koala on the reverse. A strong strike ensures sharp definition across the large fields, and specimens typically retain a brilliant uncirculated or proof-like finish, showcasing full luster and minimal contact marks.
