After decimalisation was introduced in the U.K. in 1971, the face value was kept at 25 new pence and later 25 pence (equivalent of five shillings/Crown), but the face value was not shown on any of these issues.
The first coins issued with the revised composition were in 1951 celebrating the “Festival of Britain”. Later, they were issued in 1953 commemorating the coronation of the present reigning Queen Elizabeth II with the Cupro-Nickel composition, then again in 1953 ( British Exhibition in New York), in 1965 (marking/mourning the “death of Winston Churchill”).
The term “FEDEI DEFENSOR” (Defender of the Faith) is used for Kings/Sovereigns while the term “FEDEI DEFENSATRIX” is the title given to a Queen. (Please refer my Post No. (53) “The story of the Australian Penny” posted on 12.02.12 - A reference link given at the bottom of this post). On either side of the Horse are two identical images of the Royal Crown with the inscription “E II R” (meaning Elizabeth II Regina). The coin is minted with a cupro-nickel composition.
The Obverse designer is Gilbert Ledward and the theme is “The Queen’s Coronation”.
I have purchased a five Pound Coin from the Royal Mint commemorating the Diamond Jubilee of Queen Elizabeth II.
On the reverse is her image as a young “Regina” (Queen) wearing only a laurel crown/wreath, designed by Ian Rank-Broadley, (inspired by the famous design of Mary Gillick, which is also found on the Australian penny viz:"The story of the Australian Penny” mentioned two posts before on this blog).The inscription reads "DIRIGE DEUS GRESSUS MEOS (MAY GOD GUIDE MY STEPS).
On the obverse is a present day image of the Queen designed by Ian Rank-Broadley too. The coin has the same specifications as the Crown.
