Five Pounds 2017 Platinum 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 Platinum Wedding (or 70th anniversary of the marriage) of Queen Elizabeth II to Prince Philip, Duke of Edinburgh.

The reverse was designed by John Bergdahl, and the obverse by Etienne Millner. The Royal Mint says about the design:
"A platinum wedding anniversary is a significant event for any couple. For two people who have lived their lives under the glare of public and media scrutiny, it is a testament to their unwavering devotion, strength of character and good humour.

Two sides of this world-famous yet down-to-earth couple are brought to life on this £5 coin. Etienne Millner’s combined portrait on the obverse represents a sense of duty, His Royal Highness The Prince Philip, Duke of Edinburgh supporting Her Majesty The Queen in his role of royal consort. On the reverse, John Bergdahl’s equestrian portrait captures the couple sharing their love of horses side-by-side."
