Fifty Pence 2019 Battle of Britain (NCLT), 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UK Fifty Pence coin was issued in 1969 with the classic Britannia reverse design by Christopher Ironside, which was superseded in 2008 by the Matthew Dent design for circulation coins.The denomination is also extensively used to issue circulating commemorative coins.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).

In the summer of 1940 Britain faced the threat of invasion. It would fall to brave young pilots and their crews to protect the country’s defences - the Battle of Britain had begun. It was their finest hour - who can imagine the world today if they had failed in their task?

The original coin was issued in 2015 as a circulating commemorative to mark the 75th Anniversary of the Battle of Britain.

This coin is part of the 50 years of the 50p - Brilliant Uncirculated Coin Set - Military, a 5-coin set featuring 50 pence designs on a military theme to commemorate 50 years of the denomination.

No 2019-dated coins of this type were released into circulation.
