The Royal Australian Mint has crafted a standout 2025 $1 uncirculated coin to honour the Royal Australian Corps of Signals’ 100 years of service. Established in 1925, the Corps has been pivotal in Australian military operations, delivering secure and rapid communications across a century of challenges. From pioneering electronic warfare to mastering modern cyber operations, their legacy is one of resilience and innovation. This coin, designed by Adam Ball, features Mercury, the Roman messenger god, atop a globe with a lightning bolt in hand – a powerful symbol of swift, precise communication. The Certa Cito (Swift and Sure) motto is cleverly woven into the design with Morse and binary code, blending the Corps’ storied past with its cutting-edge present.

Framed by a wreath echoing the original Corps badge, the reverse design is paired with an obverse bearing King Charles III’s effigy, sculpted by Daniel Thorne. Struck in aluminium bronze, this 25 mm, 9-gram coin boasts a mintage of 50,000 and will be available from April 3, 2025. It’s a fitting tribute to the dedication of the Corps’ members and a must-have for collectors or those who value Australia’s defence heritage. Sourced from the Mint and reputable coin circles online, this is a piece that captures a true Aussie milestone.
