Five Pounds 2007 Diamond Wedding, Coin from United Kingdom - detailed information

At the time of decimalisation in 1971, the United Kingdom Crown coin (equal to 5 shillings) was redenominated as a 25p coin and pieces struck prior to 1990 - all the way back to 1818 - continue to be legal tender for that amount. The old denomination had been a regular circulating coin in the 19th century, but in the 20th century it became more of a commemorative denomination.

The Royal Mint continued issuing commemorative coins in the same format - using the traditional coin dimensions, but in copper-nickel. These were initially also denominated as 25 pence but the "Crown" was changed in 1990 to a commemorative £5 (five pound) coin, having the same dimensions and weight but with a face value twenty times as great.

The denomination is used to mark special occasions, usually royal in theme, rather than for use in general circulation. Although not circulating, these coins are legal tender.

This commemorative £5 Crown-sized coin celebrates the Diamond Wedding (or 60th anniversary of the marriage) of Queen Elizabeth II to Prince Philip, Duke of Edinburgh. It comes ten years after another crown coin marking their Golden Wedding in 1997.

The obverse was designed by Ian Rank-Broadley, the author of the Queen's Fourth definitive portrait, and the reverse by Emma Noble.
