The fifty pence coin is a circulating denomination of the British Pound Sterling equal to a half pound.
This 50p coin design replaced the earlier 50p design by Matthew Dent, which had been in circulation since 2008. The reverse depicts an Atlantic salmon and is part of the nature-inspired recoinage introduced to mark the reign of King Charles III, reflecting his interest in conservation and nature. Wild populations of Atlantic salmon can be found in very clean rivers in Scotland and Wales along with those in North and South West England.
The chief Royal Mint engraver, Gordon Summers, oversaw the designs, alongside an advisory committee at the Royal Mint, with the involvement of the monarch himself. The Royal Mint does not credit a specific person with the reverse design, but cites it as the work of the whole team.
The 50p denomination has also been used extensively to celebrate important events by a number of circulating commemorative issues.
The coins are made of cupronickel (also known as copper-nickel; composition: 75% copper and 25% nickel). |
