Fifty Pence 2020 Rosalind Franklin, Coin from United Kingdom
CoinFifty Pence 2020 Rosalind Franklin

The British fifty pence (50p) coin - often pronounced 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UK Fifty Pence coin was issued in 1969 with the classic Britannia reverse design by Christopher Ironside, which was superseded in 2008 by the Matthew Dent design for circulation coins.The denomination is also extensively used to issue circulating commemorative coins.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 second in a series celebrating British innovators in science (the first one commemorated Stephen Hawking in 2019); it commemorates Rosalind Franklin (1920 - 1958).

Rosalind Franklin’s brilliant mind and tireless dedication enabled breakthroughs in multiple fields. Best known today for her research into DNA, Franklin was a world authority on the chemical structure of viruses, as well as coal and graphite. Tragically she died of ovarian cancer aged just 37, denying her the awards and recognition that would surely have come during her lifetime.

The Royal Mint marks what would have been Franklin’s 100th birthday with this 50p coin issued in gold, silver (Proof and Proof Piedfort) and in Brilliant Uncirculated copper-nickel; it acknowledges her immense contribution to advancing humanity’s cause.

Inspired by the historical injustice of the failure to credit Franklin’s role in determining the structure of DNA, Royal Mint graphic designer David Knapton uses the printing techniques of the era to restore her rightful legacy. By including her name in the design along with Photograph 51, the ground-breaking image she captured with Raymond Gosling of the building blocks of life, he places Franklin at the heart of the DNA story. It’s a fitting tribute to a scientist who was instrumental in enabling one of the greatest discoveries of the twentieth century.

These 50 pence coins were struck in various collector formats but none were issued into general circulation.

Obverse
United Kingdom / Fifty Pence 2020 Rosalind Franklin - obverse photo

The obverse of the coin depicts the crowned old head of Queen Elizabeth II facing right, wearing the Royal Diamond Diadem crown worn for her Coronation (effigy known as the "Fifth Portrait").

Running continuously around the effigy is the monarch's legend and the date: ELIZABETH II · D · G · REG · F · D · 50 PENCE · 2020 ·. Translated from Latin: Elizabeth the Second, by the Grace of God, Queen, Defender of the Faith, followed by the value and denomination in English and the year.

In small letters below the head, the artist's initials J.C (for Jody Clark).

Reverse
United Kingdom / Fifty Pence 2020 Rosalind Franklin - reverse photo

The reverse shows the famous first photo (known as Photo 51) providing insight into the structure of DNA, taken by Rosalind Franklin's graduate student Raymond Gosling in 1952. James Watson was shown the photo by his collaborator, Maurice Wilkins, as Raymond Gosling, the author of the picture, had returned under his supervision. Rosalind Franklin did not know this at the time because she was leaving King's College London.

Along with Francis Crick, Watson used characteristics and features of Photo 51, together with evidence from multiple other sources, to develop the chemical model of the DNA molecule. Their model, and manuscripts by Wilkins and colleagues, and Gosling and Franklin, were first published, together, in 1953, in the same issue of Nature. In 1962, the Nobel Prize in Physiology or Medicine was awarded to Watson, Crick and Wilkins. The prize was not awarded to Franklin; she had died four years earlier, and although there was not yet a rule against posthumous awards, the Nobel Committee generally does not make posthumous nominations. Likewise, Gosling's work was not cited by the prize committee.

The inscription on the coin, vertically to the right in two lines, reads ROSALIND FRANKLIN; a letter A placed next to it makes the last letters of her names part of the abbreviation DNA. To the right of that, vertically but facing in the opposite direction, Photograph 51.

The letters DK in the lower right field represent the initials of the designer, David Knapton. Value, denomination and date are on the obverse.
