The Australian dollar was introduced as a decimal currency on February 14, 1966, replacing the Australian pound. It is subdivided into 100 cents, with coins produced by the Royal Australian Mint in Canberra. While the Australian dollar does not have a quarter, the US quarter, or quarter dollar, is a coin valued at 25 cents, or one-quarter of a dollar. Australian 10-cent coins have been mistaken for US quarters due to their similar size and weight, although the Australian coin features a portrait of Queen Elizabeth II.

Australian 10 cents vs US quarter
The Australian 10-cent coin was first introduced with decimal currency on 14 February 1966. The original reverse design of the lyrebird on the standard circulating coins has been retained since its introduction. The obverse design was altered in 2016 to commemorate the 50th anniversary of decimal currency. The Australian 10-cent coin features a portrait of the Queen, which is a notable difference from the US quarter.
The Australian 10-cent coin and the US quarter are similar in size and weight, making it easy to confuse the two, especially for those unfamiliar with both currencies. However, it is important to distinguish between the two coins as they have different values. The Australian 10-cent coin is worth only 7 cents in the US, resulting in an 18-cent loss if accepted as a quarter.
Some individuals may intentionally pass off Australian 10-cent coins as US quarters, profiting from the exchange rate difference. For example, $100 USD worth of Australian 10-cent coins would amount to 1,428 coins. If these coins were passed off as US quarters, they would be worth $357 USD, resulting in a $257 USD profit.
To avoid confusion and potential financial loss, it is important to be vigilant when receiving change. The Australian 10-cent coin has a prominent "10" on one side and a portrait of the Queen on the other, making it distinguishable from the US quarter. By paying close attention to the coin's design and markings, individuals can ensure they are receiving the correct currency and value.

History of the Australian dollar
The Australian dollar (AUD) is the official currency and legal tender of Australia and its external territories, as well as three independent sovereign Pacific Island states: Kiribati, Nauru, and Tuvalu.
The history of the Australian dollar can be traced back to the early days of the colony of New South Wales in 1788, when colonists relied on barter, rum (spirits), and various international currencies, including Spanish dollars. In 1825, the British Government legislated a sterling currency for the colony, which remained the basis of Australian currency until 1966.
In 1910, a national Australian currency was created—the Australian pound, which was initially at par with the British pound. However, in 1931, the Australian pound was devalued, and from 1946 to 1971, Australia maintained a peg under the Bretton Woods system, with the Australian dollar effectively pegged to sterling until 1967.
On February 14, 1966, the Australian pound was replaced by the Australian dollar as a decimal currency, with a conversion rate of two dollars to the pound. This change was the result of a process that began in 1959, when the Commonwealth Government appointed a Decimal Currency Committee to investigate the advantages and disadvantages of a decimal currency. The introduction of the Australian dollar included the issuance of coins in denominations of 1 and 2 cents (bronze), 5, 10, and 20 cents (cupronickel), and 50 cents (silver, later cupronickel).
In 1967, Australia effectively left the sterling area when the pound sterling was devalued against the US dollar, but the Australian dollar retained its peg to the US dollar at a rate of A$1 = US$1.12. This peg was maintained until 1971 when, with the breakdown of the Bretton Woods system, Australia converted to a fluctuating rate against the US dollar.
Over the years, Australia's currency system has evolved, with the introduction of polymer banknotes in 1988 and the discontinuation of 1 and 2 cent coins in 1991. The Royal Australian Mint, established in 1969, has gained an international reputation for producing quality numismatic coins, including commemorative 50-cent coins issued since 1970.

Australian dollar as legal tender
The Australian dollar (sign: $; code: AUD) is the official currency and legal tender of Australia, including all of its external territories, and three independent sovereign Pacific Island states: Kiribati, Nauru, and Tuvalu. It was introduced as a decimal currency on 14 February 1966, replacing the non-decimal Australian pound, with a conversion rate of two dollars to the pound.
The Australian dollar is also legal tender in the external territories of Christmas Island, Cocos (Keeling) Islands, and Norfolk Island. It was formerly legal tender in Papua New Guinea and the Solomon Islands until it was replaced by their respective currencies.
In Australia, the Australian dollar is legal tender by virtue of section 36(1) of the Reserve Bank Act 1959 without an amount limit. Additionally, Section 16 of the Currency Act 1965 provides that Australian coins intended for general circulation are also legal tender, but only for specific amounts.
All previous issues of Australian banknotes and coins retain their legal tender status, although some retailers and members of the public may be reluctant to accept older banknotes due to unfamiliarity or suspicion of counterfeiting. These older notes can be redeemed at commercial banks, which may require time to confirm their authenticity.
