Australia 2025 One Dollar Centenary of Royal Australian Corps of Signal Uncirculated Coin in Card

This 2025 $1 uncirculated coin not only honours a century of dedicated service in military communications but also features a hidden message in Morse and binary code, challenging collectors and enthusiasts to decipher its secrets.

Since its establishment in 1925, the Royal Australian Corps of Signals has been vital in securing and relaying critical military communications, pioneering advancements in electronic warfare, cyber operations and defence technology. This commemorative coin pays tribute to the thousands of men and women who have safeguarded Australia’s communications on the battlefield and beyond.

Designed by Mint artist Adam Ball, the coin is rich in symbolism. At its centre stands Mercury, the Roman messenger god, reflecting the Corps’ mission of swift and secure communication. Mercury stands upon a globe, symbolising the Corps’ far-reaching impact. A wreath of leaves, reminiscent of the original Corps badge, encircles the design, while the background features Morse and binary code — a visual link between the Corps’ origins and its cutting-edge role in modern cyber warfare.
