60 Years of the Royal Australian Mint - 2025 $10 'C' Mintmark Gold Proof Coin

In 1965, Australia entered a new era with the opening of the Royal Australian Mint, a pivotal step in the nation’s transition to decimalisation. Officially inaugurated by HRH Prince Philip, the Mint has since become a symbol of Australia’s commitment to innovation and craftsmanship in coin production.

Construction began in 1963 under architect Richard Ure, requiring over a million bricks and 12,000 cubic yards of concrete. During excavation, workers unexpectedly uncovered solid stone beneath the surface—an ideal foundation for securing the Mint’s vaults.
Established to produce decimal currency, the Mint has struck over 14 billion circulating and collector coins, leaving a lasting impact both nationally and globally. Its excellence in craftsmanship has earned numerous prestigious awards in design, innovation and tourism.

The coin’s design pays tribute to the Mint’s role in shaping Australia’s numismatic heritage, acknowledging both the production processes and the skilled artisans who bring each coin to life. Designed by the Mint’s Adam Ball, this coin honours the Mint’s six-decade legacy. Adam says, “The hidden narrative pays tribute to the craftsmanship and precision behind every coin produced.” The obverse features the effigy of His Majesty King Charles III, designed by Daniel Thorne.

This design also recognizes the collectors and enthusiasts whose passion has been integral to the Mint’s success. Marking six decades of history, this coin celebrates the Mint’s lasting impact on Australia’s economic and cultural landscape.
