Halfpenny - Commonwealth of Australia, Coin Type from Australia - detailed information

Halfpenny - Commonwealth of Australia, Coin Type from Australia (issued 1911 - 1939)
Coin TypeHalfpenny - Commonwealth of Australia

The Australian halfpenny (or half penny) coin was the smallest circulating denomination of the Australian Pound; unlike the British pre-decimal Pound Sterling, the Australian Pound had no smaller denominations like the British farthings and fractional farthings.

The Australian halfpenny has the same dimensions and composition as the British pre-decimal halfpenny, from which it is derived (for a time, the coins circulated in parallel and were interchangeable in Australia - but not in the United Kingdom; the currencies were fixed at par). 1/2 penny was worth 1/24 of a shilling, or 1/480 of a pound.

The reverse of this first type of Australian halfpenny coins features text only. In 1939, a new design superseded this one - featuring the iconic leaping kangaroo; the old type of coins remained in circulation.

The coins were struck by a number of different mints; if they had mint marks for a particular year of issue, those are located under the scroll on the reverse:
- Royal Mint, 1911 - 1914, no mint mark
- Birmingham Mint (ex Heaton and Sons), 1912 - 1915, letter H
- Calcutta Mint, 1916 - 1918, letter I
- Sydney Mint, 1916 - 1926, no mint mark
- Melbourne Mint, 1923 - 1939, no mint mark

Counting the known mintages of proofs, a total of 81,157,566 (81 million) coins of this type were minted during its existence. They circulated until decimalisation and were withdrawn in 1966, when Australia switched to its current Australian Dollar currency. Unlike some of the larger denominations, they were not re-denominated into units of the new currency. However the halfpenny coins were never formally demonetised and are still legal tender for 5⁄12¢.

Effigy of the ruling British monarch, legend (in Latin). Being a Dominion of the British Empire, Australia used the Imperial legend of the monarch and not a "home" version of it.

Throughout the existence of the coin type, the monarchs were:
- King George V, 1911 - 1936, shown in his Crowned bust by Sir Edgar Bertram Mackennal
- King George VI, 1938 - 1939, shown in his Bare Head portrait by Thomas Humphrey Paget

There were no coins released for King Edward VIII.
