25 Dollars - Elizabeth II 6th Portrait - Killer Whale

The "Killer Whale" belongs to Perth Mint's ongoing Australian Orca series, which draws sustained collector interest largely because of strict annual mintage caps — typically 1,000 pieces globally for this denomination and weight. The .9999 fine gold specification reflects Perth's house standard, adopted to compete directly with the Royal Canadian Mint's Maple Leaf in the bullion-collector crossover market.

The sixth portrait of Elizabeth II, by sculptor Jody Clark, was introduced across Commonwealth coinage in 2015 and appeared on Australian issues from 2019 onward — making 2022 one of its final years of use before the Queen's death in September of that year.
