Five Pounds 2021 Prince Philip, 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 £5 Crown-sized coin commemorates Prince Philip, Duke of Edinburgh, prince consort of Queen Elizabeth II.

The Royal Mint says about it:
Following the announcement of the passing of His Royal Highness The Prince Philip, Duke of Edinburgh on 9 April 2021, many reflected that his was a life well lived. A man of action and significant achievements, Prince Philip became a naval commander at a young age and provided steadfast counsel to Her Majesty The Queen throughout her reign. When his young wife first took on the role as monarch, the newly titled Duke of Edinburgh supported her, showing tireless dedication to his duty. This exemplary service was recognised by The Queen at the time of their 70th wedding anniversary in 2017, when he was appointed a Knight Grand Cross of the Royal Victorian Order (GCVO). In honour of this remarkable man, The Royal Mint has created a coin to celebrate his life and legacy. The design features a portrait created by Ian Rank-Broadley FRBS that was personally approved by The Duke of Edinburgh in 2008.
