Throughout the 1970s and 1980s, Gibraltar issued several collector coins but no circulation coins of its own. Jersey and Guernsey had already issued their own decimal coinages in 1971, followed by the Falkland Islands in 1974. The UK demonetised its old predecimal sixpence only at the end of 1980, so that coin disappeared from Gibraltar too.
In 1982, the UK dropped the legend "NEW" from its decimal coins and introduced a circulation 20 pence coin in 1982, followed by a circulation pound coin in 1983. At the end of 1984, the halfpenny was demonetised in the UK. All these changes also took place in Gibraltar, since the UK pound sterling was still the legal currency and only UK coins and banknotes circulated there. Also in 1984, yet another British overseas territory adopted its own coinage: St Helena and Ascension.
In 1985 another major change took place in the British coinage, when the new portrait of Queen Elizabeth II, created by Raphael Maklouf, replaced the one by Arnold Machin.
In 1988 Gibraltar became the last of Britain's territories and dependencies using the UK pound sterling to issue its own coinage. The banknotes and coinage of the UK are still legal tender in Gibraltar and circulate there.
The territory uses its own currency, the Gibraltar pound. It is a separate currency from the UK pound sterling, but it is pegged to the UK pound at a rate of one to one. The Gibraltar pound is created by the Gibraltar currency board and is fully backed, 100%, by reserves of the UK pound sterling, its anchor currency. For a fuller explanation of currency boards, read this topic:
There are only four basic currency systems in the world.
The territory's coins are minted to the same specifications of size, shape, colour and weight as their UK counterparts. The UK removed any reference to "NEW" pence from its coinage in 1982, and because Gibraltar's coins were not minted until 1988, they also omitted that reference.
The reverses of the coins of Gibraltar carried designs of the local landmarks and wildlife.
All the reverse designs of 1988 - including those of the £2 and £5 collector coins, which did not circulate - were the work of local artist Alfred Ryman.
