Irish pound introduced UK versions. When the UK 5p and 10p coins were reduced in size, the Irish followed suit, but the new Irish 10p was smaller than the new UK version introduced in 1992 and the new Irish 5p was slightly larger than the UK version introduced in 1990. The Irish 50p was never reduced in size (as it had been in the UK in 1997). 31 December 1998, the exchange rates between the European Currency Unit and the Irish pound and 10 other EMS currencies (all but the pound sterling, the Swedish krona and the Danish krone) were fixed.

Currency Act 1982 Currency Act 1982 The Currency Act 1982 (c 3) is an Act of the Parliament of the United Kingdom. Following Decimal Day in 1971, when the British monetary system changed from pound/shilling/penny to the metric £1 = 100p system, the new currency was known as the "new pound" and therefore the "new pence". By 1982, the use of "new pence" was out of use, and replaced with "penny". The Act sanctions the use of "penny" rather than "new penny" in common usage, such as on coins produced by the Royal Mint. The Act covers England, Wales, Scotland and Northern Ireland.
