p) coin followed in 1969, replacing the old ten shilling note. The remaining decimal coins – at the time, the half penny (½p), 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 NEW PENNY (singular) or NEW PENCE (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).
In the years since decimalisation a number of changes have been made to the coinage. 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 note, is still in production as of 2013[ref]). The designs on the one pound coin change annually in a largely five-year cycle.
The decimal half penny coin was demonetised in 1984 as its value was by then too small to be useful. The pre-decimal sixpence, shilling and two shilling coins, which had continued to circulate alongside the decimal coinage with values of 2½p, 5p and 10p respectively, were finally withdrawn in 1980, 1990 and 1993 respectively.
In the 1990s the Royal Mint reduced the sizes of the 5p, 10p and 50p coins. As a consequence, the oldest 5p coins in circulation date from 1990, the oldest 10p coins from 1992 and the oldest 50p coins come from 1997. Since 1997, many special commemorative designs of 50p have been issued. Some of these are found fairly frequently in circulation and some are rare. They are all legal tender.
The specifications and dates of introduction of the 5p, 10p and 50p coins refer to the current versions. These coins were originally issued in larger sizes in 1968 and 1969 respectively.
With their high copper content (97%), the intrinsic value of pre-1992 1p and 2p coins increased with the surge in metal prices of the mid-2000s, until by 2006 the coins would, if melted down, have been worth about 50% more than their face value. (To do this, however, would be illegal, and they would have had to be melted in huge quantities to achieve significant gain.) In later years the price of copper fell considerably. Copper plated steel coins were introduced to replace them.
A circulating bimetallic two pound (£2) coin was introduced in 1998 (first minted in, and dated, 1997). There had previously been unimetallic commemorative £2 coins which did not normally circulate. This tendency to use the two pound coin for commemorative issues has continued since the introduction of the bimetallic coin, and a few of the older unimetallic coins have since entered circulation.
There are also commemorative issues of crowns. Before 1990 these had a face value of twenty-five pence (25p), equivalent to the five shilling crown used in pre-decimal Britain. However, in 1990 crowns were redenominated with a face value of five pounds (£5) as the previous value was considered not sufficient for such a high-status coin. The size and weight of the coin remained exactly the same. Decimal crowns are generally not found in circulation as their market value is likely to be higher than their face value, but they remain legal tender.
In 2008, UK coins underwent an extensive redesign, which changed the reverse designs, and some other details, of all coins except the £2. The original intention was to exclude both the £1 and £2 coins from the redesign because they were "relatively new additions" to the coinage, but it was later decided to include the £1 coin. This was the first wholesale change to British coinage since the first decimal coins were introduced in April 1968. The new coins were initially to be put into circulation in early 2008, although they did not actually start to appear until mid-2008.
