Coins of the pound sterling

The standard circulating coinage of the United Kingdom is denominated in pounds sterling, and, since the introduction of the two-pound coin in 1994, ranges in value from one penny to two pounds. Since decimalisation, on 15 February 1971, the pound has been divided into 100 (new) pence. From the 16th century until decimalisation, the pound was divided into 20 shillings, each of 12 (old) pence. British coins are minted by the Royal Mint in Llantrisant, Wales. The Royal Mint also commissions the coins' designs.
Twenty pence (British coin)

The British decimal twenty pence (20p) coin – often pronounced "twenty pee" – is a unit of currency equal to 20/100 of a pound sterling. 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.

Four different portraits of the Queen have been used, with the latest design by Jody Clark being introduced in 2015.

Florin (British coin)

The British florin, or two shilling coin, was issued from 1849 until 1967, with a final issue for collectors dated 1970. Valued at one tenth of a pound, it was the last coin circulating immediately prior to decimalisation to be demonetised, in 1993, having for a quarter of a century circulated alongside the ten pence piece, identical in specifications and value.
Halfpenny (British pre-decimal coin)

The British pre-decimal halfpenny coin, usually simply known as a halfpenny, historically occasionally also as the obol, was a unit of currency that equalled half of a penny or 1⁄480 of a pound sterling. Originally the halfpenny was minted in copper, but after 1860 it was minted in bronze. It ceased to be legal tender in 1969, in the run-up to decimalisation. The halfpenny featured two different designs on its reverse during its years in circulation. From 1672 until 1936 the image of Britannia appeared on the reverse, and from 1937 onwards the image of the Golden Hind appeared. Like all British coinage, it bore the portrait of the monarch on the obverse.
Threepence (British coin)

The British threepence (3d) coin, usually simply known as a threepence or threepenny bit, was a unit of currency equaling one eightieth of a pound sterling, or three old pence sterling. It was used in the United Kingdom, and earlier in Great Britain and England. Similar denominations were later used throughout the British Empire, notably in Australia, New Zealand, and South Africa.

The coin was made from silver from its introduction in 1551 to 1947, and thereafter in cupronickel.
Australian fifty-cent coin

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 the only 12-sided coin of its size in the southern hemisphere. It was introduced in 1969 to replace the round fifty-cent coin issued in 1966.
Australian ten-cent coin

The Australian ten-cent coin is a coin of the decimal Australian dollar.

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.
