25 Dollars - Elizabeth II 4th Portrait - Kangaroo - Gold Bullion Coin

Australia's four-nines fine gold bullion series, produced by the Perth Mint, sits outside the Royal Australian Mint's jurisdiction entirely — Perth operates under a Western Australian government mandate and is not a federal institution. The Kangaroo series has carried an annually changing reverse design since 1989, which distinguishes it from most sovereign bullion programs that fix their reverse imagery. The 2015 issue appeared the same year the Perth Mint was actively expanding its direct-to-investor distribution channels across Asian markets, particularly in China and Singapore, where retail bullion demand was accelerating sharply.
