The Australian 5 cent coin was first introduced with decimalisation on 14 February 1966 when it replaced the pre-decimal Australian sixpence. The original reverse design for the circulating coins (by Stuart Devlin) has not been changed since its introduction.
Occasionally, the Royal Australian Mint issues Non-Circulating Legal Tender (NCLT) 5 cent coins with different designs; however, they are not as numerous as the NCLT issues in the higher denominations such as the 50 cents, one dollar and two dollars. |
