60th Anniversary of Decimal Currency 6-Coin Set CuNi/AlBr 2026 Proof
6-Coin Set: 60th Anniversary of Decimal Currency CuNi/AlBr 2026 Proof
The 60th Anniversary of Decimal Currency set commemorates the 60th anniversary of the introduction of the decimal system in Australia, which came into effect on 14 February 1966. This event had significant social and cultural impact, changing the way money was counted across the country.
The set includes six coins struck to Proof standard, representing the full range of Australian currency denominations. Each coin is made from the metal appropriate to its denomination and adheres to official mint specifications.
5 cents: a coin struck in cupronickel (CuNi), weighing 2.83 g with a diameter of 19.41 mm. The smallest denomination in the set, forming the basis of the Australian monetary system.
10 cents: a coin in cupronickel (CuNi), weighing 5.65 g with a diameter of 23.60 mm. In this anniversary edition it features a special reverse, referencing the history of the currency before and after decimalisation.
20 cents: a coin struck in cupronickel (CuNi), weighing 11.30 g with a diameter of 28.52 mm. It retains the classic design known from circulation.
50 cents: the largest of the cupronickel coins, weighing 15.55 g with a diameter of 31.51 mm. Like the 10-cent denomination, it features a dedicated anniversary reverse, celebrating 60 years of decimal currency in Australia.
1 Australian dollar: a coin struck in aluminium–bronze (AlBr), weighing 9 g with a diameter of 25 mm. Its characteristic golden colour clearly distinguishes it from the cupronickel coins.
2 Australian dollars: a coin in aluminium–bronze (AlBr), weighing 6.60 g with a diameter of 20.50 mm. The highest denomination in the set.
Obverse of the coins: all coins feature the effigy of King Charles III, designed by Daniel Thorne, maintaining stylistic consistency across the entire issue.
The set is presented as six individually encapsulated coins, housed in a display case, accompanied by an information booklet and an outer box. The coins were struck to Proof standard by the Royal Australian Mint and are legal tender in Australia.
