The 2003 two pounds coin commemorated the 50th anniversary of the discovery of the structure of DNA.<br />
<br />
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.<br />
<br />
DNA (Deoxyribonucleic acid) is a molecule that has genetic information for the growth, development, functioning and viruses of all known living organisms.<br />

<h3>2003 Two-Pound Coin</h3>
Designed by John Mills, the reverse depicts the spiralling double helix structure of DNA with the inscription &apos;DNA DOUBLE HELIX&apos;, and dates &apos;1953&apos; and &apos;2003&apos; separated by the denomination &apos;TWO POUNDS&apos;. The edge inscription reads &apos;DEOXYRIBONUCLEIC ACID&apos;.<br />
<br />
Queen Elizabeth II&apos;s fourth portrait can be seen on the obverse, designed by Ian Rank-Broadley.<br />

<h3>Gold Two Pound DNA Coin</h3>
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 &apos;red&apos; gold, and the inner disc being &apos;yellow&apos; gold.<br />
