The British decimal twenty pence coin is a denomination of sterling coinage worth 1⁄5 of a pound. Like the 50p coin, it is an equilateral curve heptagon. Its obverse has featured the profile of Queen Elizabeth II since the coin's introduction on 9 June 1982. Four different portraits of the Queen have been used; the latest design by Jody Clark was introduced in 2015. The second and current reverse, featuring a segment of the Royal Shield, was introduced in 2008.
The British two pound (£2) coin is a denomination of sterling coinage. Its obverse has featured the profile of Queen Elizabeth II since the coin’s introduction. Three different portraits of the Queen have been used, with the current design by Jody Clark being introduced in 2015. The reverse design features Britannia.
The British crown was a denomination of sterling coinage worth 1⁄4 of one pound, or 5 shillings, or 60 (old) pence. The crown was first issued during the reign of Edward VI, as part of the coinage of the Kingdom of England.
There have been three sets of coins in Ireland since independence. In all three, the coin showed a Celtic harp on the obverse. The pre-decimal coins of the Irish pound had realistic animals on the reverse; the decimal coins retained some of these but featured ornamental birds on the lower denominations; and the euro coins used the common design of the euro currencies. The pre-decimal and original decimal coins were of the same dimensions as the same-denomination British coins, as the Irish pound was in currency union with the British pound sterling. British coins were widely accepted in Ireland, and conversely to a lesser extent. In 1979 Ireland joined the Exchange Rate Mechanism and the Irish pound left parity with sterling; coin designs introduced after this differed between the two countries.
The twelve-sided Australian fifty-cent coin is the third-highest denomination coin of the Australian dollar and the largest in terms of size in circulation. It is equal in size and shape to the Cook Island $5 coin, and both remain the only 12-sided coins in the southern hemisphere. It was introduced in 1969 to replace the round fifty-cent coin issued in 1966.
The Australian five-cent coin is the lowest-denomination circulating coin of the decimal Australian dollar introduced in 14 February 1966, replacing the pre-decimal sixpence. It has been the lowest-denomination coin in general circulation since the withdrawal of the one-cent and two-cent coins in 1992.
The Australian ten-cent coin is a coin of the decimal Australian dollar. When the dollar was introduced as half of an Australian pound on 14 February 1966, the coin inherited the specifications of the pre-decimal shilling; both coins were worth one twentieth of a pound and were called "bob". On introduction it was the fourth-lowest denomination coin. Since the withdrawal from circulation of the one and two cent coins in 1992, it has been the second-lowest denomination coin in circulation.
The Australian one-dollar coin is the second most valuable circulation denomination coin of the Australian dollar after the two-dollar coin; there are also non-circulating legal-tender coins of higher denominations.
The Australian two-dollar coin is the highest-denomination coin of the Australian dollar. It was first issued on 20 June 1988, having been in planning since the mid-1970s. It replaced the Australian two-dollar note due to having a longer circulatory life. The only "mint set only" year was 1991.
Christopher Ironside OBE, FRBS was an English painter and coin designer, particularly known for the reverse sides of the new British coins issued on decimalisation in 1971.
The Australian twenty-dollar note was issued when the currency was changed from the Australian pound to the Australian dollar on 14 February 1966. It replaced the £10 note which had similar orange colouration. There have been only three different issues of this denomination: a paper note which had a gradient of yellow and red, with a distinct orange background, and two designs of polymer note which can be recognised for their distinct red-orange colouration. The first polymer note was issued on 31 October 1994 and the Next Generation polymer banknote was issued on 9 October 2019.
The cent, formally the one-cent coin, was the lowest-denomination coin of the Australian dollar. It was introduced on 14 February 1966 in the decimalisation of Australian currency and was withdrawn from circulation in 1992. It is still minted as a non-circulating coin. A one-cent coin in 1966 would have a purchasing power equal to about 15c in 2022 values.
The round fifty cent coin was the highest-denomination and largest diameter coin of the Australian decimal coins, introduced in 1966. It has a nominal value of half an Australian dollar, the equivalent of five shillings in pre-decimal currency. Due to the large number minted in 1966, and the rising cost of silver, it was not made in any other year. It was replaced by a twelve-sided 50 cent coin in 1969, which retained its reverse of the Australian Coat of Arms.
Pre-decimal Australian coins arose when the Federation of Australia gave the constitutional power to Commonwealth of Australia to mint its own coinage in 1901. The new power allowed the Commonwealth to issue legal tender rather than individually through the six former British self-governing colonies of Queensland, New South Wales, Victoria, Tasmania, South Australia, and Western Australia.
The coins of the Australian dollar were introduced on 14 February 1966, although they did not at that time include the one-dollar or two-dollar coins. The dollar was equivalent in value to 10 shillings in the former currency.
The coins of the New Zealand dollar are used for the smallest physical currency available in New Zealand. The current denominations are ten cents, twenty cents, fifty cents, one dollar and two dollars. The $1 and $2 coins are minted in a gold colour, the 20c and 50c coins are silver colour and the 10c coin is plated in copper.
The shilling, informally called a "bob", was a type of silver coinage issued by the Commonwealth of Australia, that circulated prior to the decimalisation of Australian coinage. The Australian shilling was derived from the British pre-decimal sterling pound system and was first issued following the passing of the Australian Coinage Act 1909, which established Australia's first formal currency system. The shilling was issued as part of Australia's silver coinage, which included the two-shilling (florin), the sixpence and the threepence. The shilling was minted from 1910 until 1963. During this period there was one significant modification to the design of the Australian shilling, the change in its reverse design, which occurred in 1938 when the design was altered from the Australian Coat of Arms (1910-1936) to the visage of a Merino ram’s head (1938-1963).
The Australian sixpence circulated from 1910 up until the decimalisation of Australian Currency in 1966. The coins were initially minted in England; however, Australia began to mint their own from the year of 1916 at branches of the Royal Mint in Sydney and Melbourne. The coins which made up Australia's pre-decimal currency were identical to British currency in the characteristics of weight and size. The Coinage Act of 1909–1947, authorised the issue of Australian coins in the select denominations, including the sixpence. By 1916 all silver denominations, including the sixpence, could be minted at the Royal Mint branch in Melbourne. Unique Australian currency was created with decimalisation in 1966.
The Australian pre-decimal halfpenny coin, commonly known as a ha’penny, was the smallest denomination of the Australian Pound in circulation. It was a unit of currency that equalled half of a penny, 1/24 of a shilling or 1/480 of a pound. The coin was made to be equivalent to the British halfpenny; its dimensions, composition and values were equivalent, and additionally, the two currencies were fixed at par.
The New Zealand fifty-cent coin is a coin of the New Zealand dollar. It was the largest by denomination, diameter and mass to have been introduced on the decimalisation of the currency on 10 July 1967, replacing the pre-decimal crown coin. A total of 81,585,200 pre-2006 50 cent coins were issued, with a total value of $40,792,600.00
