United Kingdom: Coin Type One Pound (Royal Arms) (issued 1983 - )
Coin TypeOne Pound (Royal Arms)

By 1980 it had become apparent that with the general decline in purchasing power, the £1 unit of currency was more appropriate to a coin than a banknote. After consultation with many groups including retailers and special interest groups, the Government announced on 31 July 1981 that a new £1 coin that was to be issued on 21 April 1983. Since its launch the £1 has always represented the United Kingdom and its constituent parts; England, Wales, Scotland and Northern Ireland.

The £1 coin in base metal, nickel-brass was introduced in 1983, as a replacement for the £1 banknote. The reverse design of the first £1 coin showed a detailed and intricate depiction of the Royal Coat of Arms. Designed by Eric Sewell, Chief Engraver at The Royal Mint, it has become one of the most famous images on British coinage. The coin’s edge inscription is in Latin "DECUS ET TUTAMEN" which may be translated as an "ornament to safeguard".

The coin is made of Nickel-Brass , with composition of 70% copper, 5.5% nickel and 24.5% zinc.
