Fifty Pence 2023 King Charles III Coronation, Crowned Portrait, Coin from United Kingdom - detailed information

The British fifty pence (50p) coin - often pronounced as "fifty pee" - is a unit of currency equalling one half of a Pound Sterling. It is a seven-sided coin formed as an equilateral-curve heptagon, or Reuleaux polygon - a curve of constant width, meaning that the diameter is constant across any bisection. This shape, which was revolutionary at the time of its introduction, makes it easily distinguishable from round coins both by feel and by sight, while its constant breadth allows it to roll in vending machines.

The first UK Fifty Pence coin was issued in 1969 with the classic Britannia reverse design by Christopher Ironside, which was superseded in 2008 by the Matthew Dent design for circulation coins.The denomination is also extensively used to issue circulating commemorative coins.

Beginning in 2009, the Royal Mint started issuing 50 pence coins for collectors - such as this one - which are not meant to be released in circulation, so are classified as Non-Circulating Legal Tender (NCLT).

This coin was released on 24 April 2023 as part of a commemorative range celebrating the upcoming Coronation of His Majesty King Charles III at Westminster Abbey on 6 May 2023.

This is the Non-Circulating Legal Tender (NCLT) version issued for collectors only, which features a crowned version of the King's first definitive effigy, developed specially for this commemorative range.

The reverse was designed by Natasha Jenkins, who also designed the 2020 Remembrance £5 commemorative and the 2022 Commonwealth Games 50 Pence (she was then named Natasha Preece).
