Rosalind Franklin 50p Coin
2020 · Innovation in Science · Circulating
Price Guide: £4.00
Rosalind Franklin's 50p, part of the Royal Mint's Innovation in Science series, marks the chemist whose X-ray diffraction images - most famously "Photo 51" - were critical to determining the double-helix structure of DNA, work for which she received far less recognition in her lifetime than the scientists who later won the Nobel Prize for it.
Struck for general circulation, it's a common find and a popular pick among the series' science-history coins.
