Australian Coin History
In 1910, nine years after Australia federated as a nation, a national Australian currency was formed, based on the British money system of pounds, shillings and pence.
Great fortune was found in Australian soil during the gold rush in the 1800s. Gold was turned into ingots and tokens for trading, and in 1855 an official mint opened in Sydney to turn the gold into coins called sovereigns.
