The Double Helix book
The Double Helix book by James D. Watson

In 1953, James D. Watson and Francis H.C. Crick announced to the world that they had discovered the structure of DNA – the double-helix. DNA contains a person's genes and the configuration determines their genetic makeup. The double-helix structure allows a strand of DNA to replicate, splitting down the middle and then forming a whole strand again – a key process in all living things.

The reverse design by John Mills shows a representation of a strand of DNA, with the double-helix structure, containing pairs of the DNA bases (the components it is formed from - A, T, G, and C). The edge inscription states the full name of DNA – "DEOXYRIBONUCLEIC ACID", and the obverse features the 4th portrait by Ian Rank-Broadley.

Coin condition and quality

The value of a coin is always related to the condition. A Discovery of DNA Double Helix £2 Coin in good circulated condition (A few small contact marks on the coin, but retains some original shine and most of the original design detail.) is more desirable to a collector than a worn down battered coin.

Prices shown on this page relate to coins created for circulation (CIRC) and coins available to buy in Brilliant Uncirculated (BU) quality. These are coins produced to a higher standard that show more detail and have none of the marks and scratches that will be seen on all circulation quality coins.

Some coins made for circulation remain "Uncirculated" as they have been kept in or taken from the original sealed coin bag they were packed in after being sent out from The Royal Mint. These are still circulation quality coins - but may keep more of the orginal shine and have a few less contact marks.

Coins not in sealed bags or held in a collection out of the 4,299,000 coins struck, will now have been in circulation for 21 years.
