The standard circulating coinage of the United Kingdom, British Crown Dependencies and British Overseas Territories is denominated in pennies and pounds sterling, and ranges in value from one penny sterling to two pounds. Since decimalisation, on 15 February 1971, the pound has been divided into 100 pence. Before decimalisation, twelve pence made a shilling, and twenty shillings made a pound.
The crown was a denomination of sterling coinage worth a quarter of one pound. The crown was first issued during the reign of Edward VI, as part of the coinage of the Kingdom of England.
Decimal Day in the United Kingdom and in Ireland was Monday 15 February 1971, the day on which each country decimalised its respective £sd currency of pounds, shillings, and pence.
£sd, spoken as "pounds, shillings and pence", is the popular name for the pre-decimal currencies once common throughout Europe. The abbreviation originates from the Latin currency denominations librae, solidi, and denarii. In the United Kingdom, these were referred to as pounds, shillings, and pence.
The pound was the currency of Australia from 1910 until 14 February 1966, when it was replaced by the Australian dollar. Like other £sd currencies, it was subdivided into 20 shillings, each of 12 pence.
The pound is the currency of Guernsey. Since 1921, Guernsey has been in currency union with the United Kingdom and the Guernsey pound is not a separate currency but is a local issue of sterling banknotes and coins, in a similar way to the banknotes issued in Scotland, England and Northern Ireland. It can be exchanged at par with other sterling coinage and notes.
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 punt 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 punt 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 punt left parity with sterling; coin designs introduced after this differed between the two countries.
The pound was the currency of New Zealand from 1933 until 1967, when it was replaced by the New Zealand dollar. Prior to this, New Zealand used the pound sterling since the Treaty of Waitangi in 1840. Like the pound sterling, it was subdivided into 20 shillings each of 12 pence.
The pound was the official currency of Jamaica between 1840 and 1969. It circulated as a mixture of sterling coinage and locally issued coins and banknotes and was always equal to the pound sterling. The Jamaican pound was also used in the Cayman and Turks and Caicos Islands.
The florin is a coin issued for the New Zealand pound from 1933 to 1965, equal to two shillings or twenty-four pence. The coin features a kiwi on the reverse and the reigning monarch on the obverse. It was introduced in 1933 as part of the first issue of New Zealand pound coinage, due to shortages of British silver coins resulting from the devaluation of local currency relative to the pound sterling. A lengthy design process was further protracted due to differing proposed design motifs between the Royal Mint, supporting a reverse design featuring heraldic ships, and the Gordon Coates–appointed Coinage Committee's proposed kiwi design. This disagreement led to almost a dozen proposed designs and revisions before the finalised issue entered circulation in February 1934. Initially struck in silver by the Royal Mint to replace the previous imperial florin, it was struck in cupronickel from 1947 due to rising precious metal prices. While proposed as the base of a decimalised New Zealand coinage since the 1930s, the florin was ultimately replaced in 1967 by the coinage of the New Zealand dollar. Florins remained legal tender with a value of 20 cents until 31 October 2006.
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 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 British pre-decimal penny was a denomination of sterling coinage worth 1⁄240 of one pound or 1⁄12 of one shilling. Its symbol was d, from the Roman denarius. It was a continuation of the earlier English penny, and in Scotland it had the same monetary value as one pre-1707 Scottish shilling. The penny was originally minted in silver, but from the late 18th century it was minted in copper, and then after 1860 in bronze.
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
The halfpenny was first issued in New Zealand in 1940, seven years after the first introduction of a domestic pound coinage. The coin's issuing was scheduled to align with the centennial of the Treaty of Waitangi and the New Zealand centennial, alongside the penny and centennial half-crown. The coin was designed by New Zealand artist Leonard Cornwall Mitchell after winning a government-sponsored design competition, and then modelled by Royal Mint designer Percy Metcalfe. The halfpenny features the head of the reigning monarch on the obverse, with a hei-tiki pendant ornamented and simplified kowhaiwhai woodcarvings on the reverse. The smallest of all denominations of the New Zealand pound, the copper coin was worth 1/480th of a pound, or 1/120th of a crown, the largest coinage denomination. It was discontinued alongside all other New Zealand currency following decimalisation in 1967.
The Waitangi crown is a commemorative crown coin struck in 1935 by the British Royal Mint for the Dominion of New Zealand to commemorate the 1840 signing of the Treaty of Waitangi, often seen as New Zealand's founding constitutional document. It was the first five-shilling piece minted of the New Zealand pound and the nation's first coin minted primarily for collectors. Following the rejection of designs by James Berry and George Kruger Gray, Royal Mint designer Percy Metcalfe was commissioned to design the reverse. Design disagreements plagued the production of the crown, and only an extremely small mintage of 1,128 was struck and distributed to collectors. Released to muted media coverage and a general lack of interest in coin collecting during the economic aftermath of the Great Depression, the coin has become heavily sought by collectors of New Zealand coinage. Regularly selling for thousands of dollars, one pattern issue of the coin auctioned at over $70,000 USD, becoming the most expensive New Zealand coin ever sold.
The New Zealand penny is a large bronze coin issued from 1939 to 1965. Introduced seven years after the larger denominations of New Zealand pound coinage, the coin's issuing was scheduled to align with the centennial of the Treaty of Waitangi and the New Zealand centennial, alongside the halfpenny and centennial half-crown. Featuring the standard portrait of the ruling monarch on the obverse, the reverse features a tūī bird perched atop a kōwhai branch.
The New Zealand threepence is a coin of the New Zealand pound issued from 1933 to 1965. Equal to three pence, the coin was the smallest in size of all New Zealand pound coinage and the smallest in denomination of the initial 1933 issue of New Zealand pound coinage, produced due to shortages of British silver coins resulting from the devaluation of local currency relative to the pound sterling. British artist George Kruger Gray designed the coin's reverse design after an earlier pattern design featuring a hei-tiki was rejected by a coinage design committee organised by Gordon Coates. It features two crossed patu below the label "3d". Initially struck in silver by the Royal Mint, it was struck in cupronickel from 1947 onward due to rising precious metal prices. Following decimalisation in 1967, the threepence was replaced by the coinage of the New Zealand dollar.
The half-crown is the largest of five denominations of New Zealand pound coinage first issued in 1933. Introduced due to shortages of comparable British silver coinage following the devaluation of the New Zealand pound relative to the pound sterling, the coin measures roughly 32 mm (1.3 in) in diameter. It was equal to thirty pence, two and a half shillings, or an eighth of a pound.
The Centennial half-crown is a commemorative coin of the New Zealand half-crown released in 1940 to coincide with the hundredth anniversary of the Treaty of Waitangi. A 1938 government-sponsored design competition for the commemorative half-crown, alongside the concurrently released penny and halfpenny, was won by New Zealand artist Leonard Cornwall Mitchell. The coin features a Māori woman surrounded by traditional Māori architecture on her right, a modern cityscape on her left, and a rising sun behind her head. The coin, like other contemporary New Zealand half-crowns, had a diameter of 32 mm and a weight of 14.14 grams, and was struck by the Royal Mint in .500 fineness silver. Unlike the Waitangi crown, the first New Zealand commemorative issue, a large mintage of 100,800 coins was produced and released directly into circulation at face value. However, the popularity of the coin led to it rapidly exiting circulation into private collections.
