The Australian Penny was a coin of the Australian pound used in the Commonwealth of Australia prior to decimalisation in 1966. It was worth one twelfth of an Australian shilling and 1/240 of an Australian pound. The coin was equivalent in its dimensions, composition and value to the British penny, as the two currencies were fixed at par.
The coin was first introduced in 1911, and stopped being minted in 1964, with the introduction of decimalisation. When decimalisation happened on 14 February 1966, the coin value was equal to 0.8333¢.
The obverse of the coin featured the reigning Australian monarch. Three were featured: George V, George VI and Elizabeth II. All of the pennies featuring George VI and Elizabeth II had a kangaroo on the reverse. The same image was on the Australian half-penny and has since been included on the dollar coin and the bullion silver kangaroo.
During the George VI era, coins minted at Melbourne had a dot at the end of the word "PENNY", while coins from Perth did not have a dot. This continued through the end of the coin's lifetime.
Counting the known mintages of proofs, a total of 814,788,088 (815 million) coins of the denomination were minted during its existence.
