5 Dollars - Elizabeth II 4th Portrait - 150 Years of State Government South Australia - Silver Proof

Historical Context: Issued in 2007, this Australian 5 Dollar silver proof coin commemorates the 150th anniversary of State Government in South Australia. The year 1856 marked the establishment of responsible government in the colony, a pivotal moment in Australia's democratic evolution and South Australia's pioneering role. The coin features the fourth portrait of Her Majesty Queen Elizabeth II by Ian Rank-Broadley, a prominent effigy used across Commonwealth coinage during the early 21st century.

Artistry: The obverse design showcases Ian Rank-Broadley's acclaimed fourth effigy of Queen Elizabeth II, facing right, adorned with the Girls of Great Britain and Ireland Tiara. This portrait exemplifies a contemporary classical style, emphasizing dignity. The reverse, designed by Wojciech Pietranik, presents a detailed rendition of Parliament House in Adelaide. Its architectural precision and symbolic choice underscore the commemorative theme, rendered in a realistic style characteristic of modern Australian numismatics.

Technical/Grading: Struck as a proof coin from .999 fine silver, weighing 36.31 grams and measuring 38.74 millimeters, this issue exhibits superior technical qualities. High-points on the obverse include the Queen's tiara and hair. On the reverse, Parliament House's architectural elements, particularly its dome and columns, are critical for assessing strike quality. Proof coins are characterized by highly polished fields and frosted devices, creating a striking cameo effect, indicative of careful production.
