Darwin Day site offers free registration and display of all Darwin Day events. The Perth Mint, Australia will launch a 2009 dated commemorative 1 ounce silver legal tender coin depicting Darwin, young and old; HMS Beagle; and Darwin's signature. Some celebrants also combine Darwin Day with a celebration of Abraham Lincoln, who was also born on 12 February 1809. Still others like to celebrate the many noted individuals that influenced or were influenced by Darwin's work, such as Thomas H. Huxley, Charles Lyell, Alfred Russel Wallace, Carl Sagan, and Ernst Mayr. Support for Darwin Day comes from both secular and religious organisations.
