Twenty cent - 1966 to 1984 - Price Guide
Twenty cent Australian coins showing an Platypus on reverse were released for the first time in circulation on February 14, 1966. Like the four species of echidna, the platypus is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth to live young. The platypus is the animal emblem of the state of New South Wales. Until the early 20th century humans hunted the platypus for its fur, but it is now protected throughout its range.
