Five Pounds 2022 Duke of Cambridge Birthday, 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 commemorative coin is part of a series celebrating the 40th birthday of HRH The Duke of Cambridge (Prince William).

The Mint says about it:
Growing up during the eighties and nineties as a popular prince, His Royal Highness The Duke of Cambridge has evolved into his senior royal role with seamless confidence. In addition to his ceremonial duties, which include supporting his grandmother, Her Majesty The Queen, His Royal Highness works tirelessly to make an impact on progressive causes that remain close to his heart - whether it’s tackling the issue of climate change or the stigma attached to mental health issues. As a devoted husband to Her Royal Highness The Duchess of Cambridge and a loving father to their three young children, this year The Duke of Cambridge celebrates his milestone 40th birthday.
