60th Anniversary of Decimal Currency 2026 $10 1/10oz Gold Proof Coin

In 2026, the Royal Australian Mint celebrates the 60th anniversary of Australian decimal currency by exploring six decades of our shared numismatic history. Ausralia in the 1960s was a young country wanting to assert itself on the world stage. The changeover to decimal currency was a symbolic and practical part of this. The government's public education campaign, with the adorable cartoon character "Dollar Bill", helped Australians make the changeover on 14th February 1966 without a hitch. While Stuart Devlin's iconic and enduring circulating coin designs remain a timeless testament to this aspirational endeavour. Since then the Mint and Australian coins have adopted to the changing times and requirements. The original round, and 80 per cent silver, 50c coin was updated to cupronickel and given its distinctive 12 sided dodecagon shape from 1969. The $1 coin was introduced in 1984, followed by the $2 coin in 1988. While the 1c and 2c coins were withdrawn from circulation in 1992.
