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UK Fifty Pence coin was issued in 1969 with the classic Britannia reverse design by Christopher Ironside, which was superseded in 2008 by the Matthew Dent design for circulation coins.The denomination is also extensively used to issue circulating commemorative coins.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).
To celebrate the 150th anniversary of the birth of Beatrix Potter - famous writer of children's books, the Royal Mint released a circulating commemorative 50p coin in 2016 to celebrate Beatrix Potter herself. All designed by Emma Noble, further coins were issued in 2016 featuring favourite characters from her books: Peter Rabbit, Jemima Puddle-Duck, Mrs. Tiggy-Winkle and Squirrel Nutkin. Due to the great success of the coins, the Royal Mint continued the series in 2017 with a different coin featuring Peter Rabbit again, then Tom Kitten, Mr. Jeremy Fisher and Benjamin Bunny. In 2018 they were followed by yet another Peter Rabbit coin, then Mrs. Tittlemouse, The Tailor of Gloucester and Flopsy Bunny.
This fourth Peter Rabbit 50p coin continues the series with a new rendition of the favourite story character. It was released in Brilliant Uncirculated grade in a presentation folder (Royal Mint Product Code: UK19PRBU, Issue Price: £10.00), as well as a coloured silver proof and a gold proof.
No coins of this type were released into circulation. |
