'Coincryption': New Aussie 50 Cent Coins Feature Cold-War-Era Encrypted Codes

A limited-edition new 50 cent coin has been released by the Royal Australian Mint featuring encrypted codes that are similar to the ones used by Australian Cold War operatives decades ago.

And if that's not enough to get your spy-senses tingling, the Mint has also launched a new competition 'Coincrypton' which will see one lucky Aussie win the country's only ASIO-designed proof coin in existence.

Proof coins are rare in themselves and are often used for archival purposes and made from the highest quality.

The new coins, released this week, are all in commemoration of the 70 Year Anniversary of the establishment of the Australian Security Intelligence Organisation (ASIO) in 1949, during the Cold War era.

ASIO's Director-General of Security Duncan Lewis said the intriguing theme of spies has often been seen in novels and films and was now "excited" to see it re-imagined in the "creative and enduring way" of Australian coins.

"2019 is a milestone year for ASIO offering a natural point of reflection, to commemorate our history, and celebrate our success, our people and our cultures," Lewis said.

Royal Australian Mint CEO Ross MacDiarmid said the Coincryption competition celebrated the elusive world of spies and espionage, adding that the new coins feature "an encrypted code similar to that used by operatives during the Cold War."

If you're keen to get your hands on this limited edition coin, you'll have to get in quick. There are only 20,000 of the uncirculated coins being made available for purchase, with each coin selling at $10.

Those who purchase the special edition coin, can then enter and be part of the competition to win the one-of-a-kind ASIO proof coin up until December 2.

But -- like all good spy stories -- there's a catch... you'll have to decipher the secret symbols and coded message on your coin first.

Time to flex your spy skills and get those detective caps on.
