( December 2015 ) Halfpenny United Kingdom Value 0.005 pound sterling Mass 1.78 g Diameter 17.14 mm Thickness 1 mm Edge plain Composition bronze Years of minting 1971 -- 1984 Obverse Design Queen Elizabeth II Designer Arnold Machin Design date 1971 Reverse Design St Edward 's Crown Designer Christopher Ironside Design date 1971 The British decimal halfpenny ( 1⁄2p ) coin was introduced in February 1971, at the time of decimalisation, and was worth one two - hundredth of a pound sterling. It was ignored in banking transactions, which were carried out in units of 1p. The decimal halfpenny had the same value as 1.2 pre-decimal pence, and was introduced to enable the prices of some low - value items to be more accurately translated to the new decimal currency. The possibility of setting prices including an odd half penny also made it more practical to retain the pre-decimal sixpence in circulation ( with a value of 21⁄2 new pence ) alongside the new decimal coinage. The halfpenny coin 's obverse featured the profile of Queen Elizabeth II ; the reverse featured an image of St Edward 's Crown. It was minted in bronze ( like the 1p and 2p coins ). It was the smallest decimal coin in both size and value. The size was in proportion to the 1p and 2p coins. It soon became Britain 's least favourite coin. The Treasury had continued to argue that the halfpenny was important in the fight against inflation ( preventing prices from being rounded up ). The coin was demonetised and withdrawn from circulation in December 1984.

Only one design of obverse was used on the halfpenny coin. The inscription around the portrait on the obverse was ELIZABETH II D.G. REG. F.D. 19xx, where 19xx was the year of minting. Both sides of the coin are encircled by dots, a common feature on coins, known as beading. As on all decimal coins produced before 1984, the portrait of Queen Elizabeth II by Arnold Machin appeared on the obverse ; in this portrait the Queen wears the ' Girls of Great Britain and Ireland ' Tiara.
