1000 Dollars - Elizabeth II 6th Portrait - Kimberley Sunset

The Kimberley Sunset coin is part of Perth Mint's ongoing high-denomination series exploiting Australia's 22-carat gold standard — the same fineness used for sovereigns under the pre-decimal system, retained here by deliberate institutional choice rather than accident. At 155.5 grams, the planchet corresponds to five troy ounces, a denomination structure Perth has used consistently across its bullion and numismatic crossover issues to justify the four-figure face value against spot.

The 6th portrait of Elizabeth II, by Jody Clark, was introduced to Australian coinage in 2019 — later than most Commonwealth realms adopted it.
