DNA was actually discovered quite a long time ago
The 2003 two pounds coin commemorated the 50th anniversary of the discovery of the structure of DNA.
Despite it being a modern buzz-word, DNA was actually discovered quite a long time ago. DNA was first isolated by Friedrich Miescher in 1869 but the molecular structure was identified by James Watson and Francis Crick in 1953 using data acquired by X-Ray Physicist Raymond Gosling.
DNA (Deoxyribonucleic acid) is a molecule that has genetic information for the growth, development, functioning and viruses of all known living organisms.
2003 Two-Pound Coin
Designed by John Mills, the reverse depicts the spiralling double helix structure of DNA with the inscription ‘DNA DOUBLE HELIX’, and dates ‘1953’ and ‘2003’ separated by the denomination ‘TWO POUNDS’. The edge inscription reads ‘DEOXYRIBONUCLEIC ACID’.
Queen Elizabeth II’s fourth portrait can be seen on the obverse, designed by Ian Rank-Broadley.
Gold Two Pound DNA Coin
The Royal Mint also issued this coin in gold proof, interesting to collectors to see how a bimetallic coin could be reproduced in gold. The Royal Mint did this cleverly by making the outer disc out of ‘red’ gold, and the inner disc being ‘yellow’ gold.
The two pounds piece is made of solid 22 carat gold (Gold Fineness of 0.916), and weighs 15.98 grams. It has a diameter of 28.40mm.
