By Royal Proclamation of 22nd June 1983, Her Majesty Queen Elizabeth II authorised four new designs for the reverse of the one-poiund coin. The four designs, adopted in turn for the years 1984 - 1987, represent Scotland, Wales, Northern Ireland and England.
To commemorate this significant occasion in the history of the United Kingdom coinage, the Royal Mint issued 50,000 proof coins in silver of each design. Within this issue limited, a number have been reserved for inclusion in a four-coin collection case.
The reverse designs, all including the Royal Diadem, show a thistle for Scotland, a leek for Wales, a flax plant for Northern Ireland and an oak tree for England. These are the work of distinguished silversmith, Leslie Durbin. The obverse of the Scottish coin bears the Arnold Machin portrait of The Queen, while the new effigy by Raphael Maklouf appears on the other three coins.
The edge inscription on the Scottish coin reads Nemo Me Impune Lacessit, (no-one provokes me with impunity) and on the Welsh coin Pleidio Wyf I'm Gwlad (true am I to my country). The coins representing Northern Ireland and England have the traditional words Decus et Tutamen (an ornament and a safeguard).
