Fifty Pence 2024 Iconic Specimens - Tyrannosaurus, 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UK Fifty Pence coin was issued in 1969 with the classic Britannia reverse design by Christopher Ironside, which was superseded in 2008 by the Matthew Dent design for circulation coins.The denomination is also extensively used to issue circulating commemorative coins.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 50p commemorative coin is the first issue in the Iconic Specimens collection, part of Tales of the Earth series of coins, and features the iconic Tyrannosaurus.

The design was developed in collaboration with the Natural History Museum, and features original artwork created specifically for this collection by renowned palaeo-artist Robert Nicholls, based on scientifically accurate reconstructions.

No coins of this type were released into circulation.
