For the last 70 years the Australian Security Intelligence Organisation (ASIO) has protected Australia, its citizens and its interests from those who would seek to do us harm. This evocative 50c uncirculated coin commemorates ASIOs ongoing efforts to protect us. The coin design includes a unique one-time pad list of random letters that were used by operatives during the Cold War, to encrypt and decode secret messages.
