Historical Context: The 2007 Australian 1 Dollar Koala Silver Bullion Coin was issued during Queen Elizabeth II's reign, featuring her fourth definitive portrait. This coin marked the inaugural release of the Perth Mint's annual Koala series, establishing a new pillar in Australia's esteemed bullion program alongside the Kookaburra and Kangaroo series. Its introduction reinforced Australia's commitment to the global precious metals market, blending investment appeal with collectible artistry.
Artistry: The obverse displays Ian Rank-Broadley's dignified fourth effigy of Queen Elizabeth II, a recognized Commonwealth portrait since 1998. The reverse features the captivating inaugural Koala series design, depicting a naturalistic representation of Australia's iconic marsupial. While specific reverse engraver details are often proprietary to the Perth Mint, the design adheres to a modern realistic stylistic school, emphasizing lifelike detail and capturing the koala's unique charm.
Technical/Grading: Struck in .999 fine silver, weighing 31.1035 grams and 40.6 mm in diameter, this bullion coin typically exhibits a brilliant uncirculated (BU) finish. Key high-points for grading include the Queen's hair on the obverse, and the delicate fur texture and facial features of the koala on the reverse. A strong strike is characteristic, ensuring sharp definition across design elements and often a pleasing contrast between frosted devices and reflective fields, indicative of a well-executed bullion product.
