A new coin released by the Royal Australian Mint celebrates the Centenary of the Royal Australian Corps of Signals - but not all is at it seems.

Beneath its golden facade, the $1 commemorative coin features a hidden message in code, just waiting to be cracked.

"[There are] some amazing design features of the coin, capturing our heritage," Royal Australian Corps of Signals Head of Corps, Brigadier Deane Limmer, said.

Coin rich in symbolism and history

The Royal Australian Corps of Signals was established in 1925, and celebrates 100 years of service in military communications this year.

Part of their role has been to provide communications, information systems and electronic warfare support to the Australian Army and the Australian Defence Force.

"Signallers have been at the forefront of technology, even back in the day," Brigadier Limmer said.

More than a collectible

Ms Martin said it was "such an honour for the Royal Australian Mint to be helping to celebrate the centenary of the Royal Australian Core Signals today".

"It is not just a collectible," she said.

"It is a reminder of the ingenuity, sacrifice and strategic brilliance that has protected Australia for a century [and] a tribute to the men and women who have placed service above self, securing the nation's defences through the power of communications."

Ms Martin added that there would always be a place for collectors at the Mint.
