The Australian 50 cent denomination was first introduced as a silver coin with decimalisation on 14 February 1966, but was changed in 1969 to its current specifications: a large dodecagonal (12-sided) copper-nickel coin; apart from the usual design featuring the Australian Coat of Arms, the denomination is also extensively used to issue circulating commemorative coins with various reverses. It is one of the heaviest coins in regular circulation in the world.
Apart from circulating coins, the Royal Australian Mint has a range of Non-Circulating Legal Tender (NCLT) 50 cent coins issued for collectors, such as this one.
This coin design was issued as part of the Royal Australian Mint's annual baby coin sets, which the mint has been releasing annually since 1995. The 2025 set, named Aussie Bubs (from Australian: Australian Babies) continues the tradition of joyously celebrating all things baby, coin and collecting. Inspired by traditional designs, these coins have a fresh, whimsical twist. Elyssa Waterford's design beautifully capture Australia’s wildlife, where "Kim the koala clings to gum leaves on the 50 cent coin, with coins hidden behind her".
No coins of this type have been released into circulation. |
