1 oz Australian Kangaroo Mixed Years — forty years of Perth Mint's annually changing reverse
1 oz Australian Kangaroo Mixed Years is a gold bullion coin from Perth Mint with a fineness of 999.9/1000 and a mass of 31.103 g of fine gold, belonging to the flagship Australian series launched in 1986. The Mixed Years variant covers a randomly selected vintage from the manufacturer's warehouses — typically from 1986-2024 — in the original Perth Mint individual capsule.
The Kangaroo series stands out for a principle unique in precious metals numismatics: an annually changing reverse. Each vintage presents a different kangaroo motif while retaining identical technical parameters and the same 100 AUD face value. This solution gives the coin a collector dimension while preserving its full bullion status with LBMA Good Delivery accreditation.

History of the Australian Kangaroo series
The series was launched in 1986 under the original name "Australian Nugget" — the reverse then featured historical Australian nuggets such as the famous "Welcome Stranger" discovered in 1869. Perth Mint's decision to give the coin a motif evoking the heritage of gold mining at Kalgoorlie and Coolgardie from the 1890s firmly anchored the series in local tradition.
In 1989 Perth Mint made a breakthrough change: the reverse motif became the kangaroo — Australia's national animal — while preserving the principle of annual design changes. In 1990 the fineness was raised from 999/1000 to 999.9/1000, matching the competing series of the time: Maple Leaf (since 1979) and Vienna Philharmonic (since 1989). The name change from "Nugget" to "Kangaroo" was formalised in international trade in the early 1990s.
The annual reverse change is a defining feature of the Kangaroo among classic bullion coins. The Maple Leaf has retained Walter Ott's maple leaf since 1979, the Krugerrand has kept Coert Steynberg's springbok since 1967, and the Vienna Philharmonic has shown Thomas Pesendorfer's Viennese organ since 1989. Only the Kangaroo presents a different main reverse motif each year, turning the series into a collector path within the bullion segment.
The most recognisable reverses include the "Red Kangaroo" from 1989, "Kangaroo with Joey" (mother with young) from 2007, the jubilee motif "25 Years of Australian Nugget" from 2012, and "Western Grey Kangaroo" from the 2025 vintage. Since 2024 the obverse of the coin presents the new portrait of King Charles III by Martin Jennings, replacing the earlier portrait of Queen Elizabeth II by Ian Rank-Broadley.
Perth Mint currently belongs to Gold Corporation — an agency of the Government of Western Australia. After reorganisation in 1970 the mint passed under state government control, making it a unique structure among the world's national mints: the issuer role is held by a state government, not a federation. The LBMA Good Delivery accreditation, maintained since the early 20th century, confirms the global status of Perth Mint's production.
Obverse — portrait of the monarch
The obverse of the 1 oz Kangaroo presents the currently valid portrait of the British monarch — in vintages 1986-2023 it is the image of Queen Elizabeth II, designed by Ian Rank-Broadley in 1998 (replacing the earlier portrait by Raphael Maklouf). Around the portrait is the inscription ELIZABETH II together with the face value 100 DOLLARS and the AUSTRALIA signature.
Since 2024 the obverse of the coin presents the new portrait of King Charles III by Martin Jennings — the first artist whose design was officially approved by the monarch after his accession to the throne in September 2022. The portrait of Charles III on Commonwealth coins (including Australian coins) shows the monarch facing left — in accordance with the heraldic tradition of changing portrait direction between successive monarchs.
Reverse — kangaroo motif and annually changing design
The reverse of the 1 oz Australian Kangaroo presents the kangaroo motif — Australia's national animal — in an annually changing variant. The first reverses from 1989-1990 were created on the basis of designs by Stuart Devlin, the Australian goldsmith and royal designer. In subsequent years Perth Mint introduced new motifs: the leaping kangaroo, the kangaroo with joey, the Red Kangaroo, the Western Grey Kangaroo, and others.
Around the central motif is the inscription AUSTRALIAN KANGAROO and the year of minting (different for each coin in the Mixed Years variant), the mass 1 OZ. 9999 GOLD and the Perth Mint mark in the form of the letter P. Since 2018 Perth Mint has introduced a security feature in the form of a micro-engraved two-letter signature around the central motif, visible only under a loupe with at least 5x magnification.
What to watch for when buying
In the case of the Mixed Years variant, it is worth verifying the overall preservation state of the coin — the Perth Mint individual capsule should be undamaged, without signs of opening, and the coin itself should be free of visible scratches on the main surfaces. Minor circulation marks on the edge are acceptable in this variant.
The Mixed Years variant does not allow selection of a specific vintage — the coin comes from current Perth Mint warehouses and its year of minting is random within the range 1986-2024. Customers interested in a specific vintage (e.g. the 2012 jubilee issue or the first Charles III vintage from 2024) should consider buying a single vintage issue.
Bullion product status: the Kangaroo holds LBMA Good Delivery accreditation and is classified as a bullion coin under Council Directive 98/80/EC (the 999.9 fineness exceeds the required minimum of 900/1000 for bullion coins in the EU). The 100 AUD face value confirms legal tender status in Australia.
The micro-engraved security features present on vintages from 2018 onward are an additional authentication element — they require a loupe with at least 5x magnification. Earlier vintages (1986-2017) do not have this feature but are verifiable on the basis of mass, diameter and thickness in line with Perth Mint specification.
