The Royal Australian Mint celebrates a golden milestone with the 2025 $10 'C' Mintmark Gold Proof Coin, marking 60 years since its 1965 opening by HRH Prince Philip. This coin honours the Mint’s legacy in Australia’s decimalisation journey, having struck over 14 billion coins since its construction began in 1963 under architect Richard Ure, using over a million bricks on a solid stone foundation. Designed by Adam Ball, the coin features a prominent “60” with “1965-2025,” surrounded by vignettes of the Mint’s history – from its production processes to its iconic Canberra building – paying tribute to the artisans behind its award-winning craftsmanship.

Struck in gold with a proof finish, this $10 coin bears the “C” mintmark for Canberra, reflecting the Mint’s home base, with a limited mintage of 2,025, making it a rare treasure. The obverse showcases the effigy of King Charles III, designed by Daniel Thorne, blending tradition with this anniversary celebration. Housed in a sleek black presentation case with a certificate of authenticity, the outer box features a historical image of the Mint’s early days, set against a modern design. This coin is a stunning tribute to the Mint’s six-decade impact on Australia’s economic and cultural landscape, perfect for collectors and enthusiasts who’ve supported its journey.
