chains (the badge of the Houses of Parliament). Two pence, 1971–2007: The Prince of Wales's feathers: a plume of ostrich feathers within a coronet. Five pence, 1968–2007: The Badge of Scotland, a thistle royally crowned. Ten pence, 1968–2007: The lion of England royally crowned. Fifty pence, 1969–2007: Britannia and lion. The first decimal coins – the five pence (5p) and ten pence (10p) — were introduced in 1968 in the run-up to decimalisation in order to familiarise the public with the new system. These initially circulated alongside the pre-decimal coinage and had the same size and value as the existing one shilling and two shilling coins respectively. The fifty pence (50p) coin followed in 1969, replacing the old ten shilling note. The remaining decimal coins – at the time, the half penny (p), penny (1p) and two pence (2p) — were issued in 1971 at decimalisation. A quarter-penny coin, to be struck in aluminium, was proposed at the time decimalisation was being planned, but was never minted. The new coins were initially marked with the wording (singular) or (plural). The word "new" was dropped in 1982. The symbol "p" was adopted to distinguish the new pennies from the old, which used the symbol "d" (from the Latin denarius, a coin used in the Roman Empire). Updates 1982–1998 In the years since decimalisation, a number of changes have been made to the coinage; these new denominations were introduced with the following designs: Twenty pence, 1982–2007: A crowned Tudor Rose, a traditional heraldic emblem of England (with incuse design and lettering). One pound, 1983–2016: various designs; see One pound (British coin). Two pounds, 1997–2014: An abstract design of concentric circles, representing technological development from the Iron Age to the modern-day electronic age. Additionally: The halfpenny was discontinued in 1984. The composition of the 1p and 2p was changed in 1992 from bronze to copper-plated steel without changing the design. The sizes of the 5p, 10p and 50p coins were reduced in 1990, 1992 and 1997, respectively, also without changing the design. The twenty pence (20p) coin was introduced in 1982 to fill the gap between the 10p and 50p coins. The pound coin (£1) was introduced in 1983 to replace the Bank of England £1 banknote which was discontinued in 1984 (although the Scottish banks continued producing them for some time afterwards; the last of them, the Royal Bank of Scotland £1
