Honouring the 50th anniversary of the Battles of Coral & Balmoral - a series of fierce actions during the Vietnam War, and a watershed moment for Australian forces - this new 50c will not be issued for circulation. As it will never be found in change, the opportunity to keep your collection complete must be grasped with both hands. Unique, each Unc coin is set in a RAM pack. Mintage a mere 30,000!
