Two Pounds 2009 Charles Darwin, Coin from United Kingdom - detailed information

The bi-metallic £2 coin is the largest circulating coin denomination of the Pound Sterling. It was introduced in 1998 (earlier two pound coins were made of Nickel brass, were intended as commemorative, and did not circulate much). Being bi-metallic means that the coin comprises two separate components of differing alloys - a Nickel-Brass outer ring with inner circle of CuproNickel.

The Royal Mint maintains a "definitive" style of the £2 issued annually, as well as a large variety of one-year circulating commemorative types and some Non-Circulating Legal Tender (NCLT) £2 coins for collectors. Between 1997 and 2015, the definitive type was the Technology type £2, which was then changed to the Britannia type £2.

The one-year type coins celebrate important anniversaries or people, as well as iconic aspects of British culture and history.

This circulating commemorative £2 coin marks the 200th anniversary of the birth of Charles Darwin, as well as the 150th anniversary of the publication of On the Origin of Species.

Charles Robert Darwin (1809 - 1882) was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history, and he was honoured by burial in Westminster Abbey.

Darwin published his theory of evolution with compelling evidence in his 1859 book "On the Origin of Species". By the 1870s, the scientific community and a majority of the educated public had accepted evolution as a fact. However, many favoured competing explanations which gave only a minor role to natural selection, and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution. Darwin's scientific discovery is the unifying theory of the life sciences, explaining the diversity of life.

£2 coins issued in 2009 have now been in circulation for 16 years.
