Australian Pre-Decimal Coins

Australian pre-decimal coinage was issued between 1910 and 1964, prior to the introduction of decimal currency in 1966. These coins followed the British £/s/d (pounds, shillings, and pence) monetary system that was in use throughout Australia during this period.

Denominations within the pre-decimal series included the Halfpenny (½d), Penny (1d), Threepence (3d), Sixpence (6d), Shilling (1/-), Florin (2/-), and Crown (5/-).

Metal composition varied by denomination and period. Silver coins—specifically the Threepence, Sixpence, Shilling, and Florin—were struck in 92.5% sterling silver up until 1946. From 1946 onward, these denominations were issued in a reduced silver content of 50%.

Minting locations evolved over time. Early Australian pre-decimal coins were produced in the United Kingdom, while local minting commenced with the establishment of the Melbourne branch of the Royal Mint in 1910. Production later expanded to include the Perth and Sydney mints, reflecting the growth of Australia’s domestic minting capability.
