正面描述 The fourth portrait effigy of Queen Elizabeth II, designed by Ian Rank-Broadley, occupies the center of the obverse, depicted in right-facing profile with a tiara and wearing a pearl earring. The legend ELIZABETH II flanks the upper field to the left, with AUSTRALIA 2014 continuing around the right, all separated by raised dot stops. The denomination 1 DOLLAR appears in the lower field, also separated by dot stops. The engraver's initials IRB are incised beneath the truncation of the neck. The coin displays a deeply mirrored proof field characteristic of Perth Mint production.

附加信息

Procoptodon goliah, the giant short-faced kangaroo, stood roughly three metres tall and is estimated to have gone extinct around 46,000 years ago — likely a casualty of the combined pressures of human arrival in Australia and climatic aridification. This coin is part of Perth Mint's Australian Megafauna series, which used pad printing to apply colour directly onto the silver field, a technique Perth was actively refining during this period to achieve more nuanced tonal gradations than enamel inlay allows.
