Fifty Years of the 50 Cent Coin: Celebrating Australia’s Unique 12-Sided Coinage

By Royal Australian Mint ……
 

The 50th Anniversary of the introduction of the copper-nickel dodecagon 50 cent coin is celebrated today with a new limited edition collectible coin set by the Royal Australian Mint. Celebrating not only 50 years but also five different effigies that have featured on the coins since 1969.

“This year Australia commemorates the 50th anniversary of Australia’s most distinctive decimal coin. The most iconic for its unusual shape, it’s the coin that has launched many into a world of coin collecting,” said Royal Australian Mint CEO Ross MacDiarmid.

Mr. MacDiarmid said the Royal Australian Mint is excited to share a special limited edition release featuring a gold-plated 50 cent coin to mark its golden anniversary.

When decimal currency was introduced in 1966, the 50 cent coin was the showpiece of the new circulating coins. The coins were made of silver, round in shape, and featured the Commonwealth Coat of Arms.

In 1968 the Royal Australian Mint ceased production of the coins, as silver prices started to rise above the face value of the coins. The new coins, released in 1969, were dodecagonal (12-sided) in shape, and manufactured in a copper-nickel alloy. The new coin shape differentiated the 50 cent coins more easily from the round 20 cent coins.

In the time since its introduction in 1969, the coins have borne five different effigies of Her Majesty Queen Elizabeth II, and a range of commemorative designs, making them attractive to collectors.

The ‘2019 50c Uncirculated Coin Set – 50th Anniversary of the 50c’ is available in a limited mintage of 20,000, retailing for $65.00 AUD.

The coins are Australian legal tender and can be purchased from the Mint’s website or Contact Centre (1300 652 020).
