bottom, and "United States of America" appears at the top. When the islands became a US Commonwealth, the arms of the Commonwealth were adopted. This seal is composed of a much smaller eagle with its wings pointed up, perched over a shield with peaked corners, above a scroll reading "Commonwealth of the Philippines". It is a much busier pattern, and widely considered less attractive. Coins were minted at the Philadelphia, San Francisco, Denver, and (after it was opened in 1920) Manila mints. Most of the coins struck at the Manila mint occurred after 1925. Proof sets were struck for collectors from 1903 to 1908. It is likely that a large majority of these sets remained unsold at the time they were issued. The recorded mintage for sets in 1905, 1906, and 1908 is a modest 500. Defenders of Corregidor threw a large number of silver coins into the ocean, rather than allow the Japanese to accumulate this wealth. A great deal of the booty was later recovered, but many of those were badly corroded. Among the rarest coins in the U.S. Philippines series from the collectors' standpoint are the 1906-S One Peso, the 1916-S Five Centavos, the 1918-S Five Centavo Mule, the 1903-S Twenty Centavos (especially in Mint State) and the 1915-S One Centavo. Three Commemorative coins were minted to celebrate the Commonwealth in 1936. They show President Franklin D. Roosevelt, Commonwealth President Manuel L. Quezon and U.S. High Commissioner Frank Murphy, who also has served as the last Governor General of the Islands. The 50 Centavo commemorative has a reported mintage of 20,000 pieces, was struck in 75% silver, and weighs 10 grams (the same specifications as other 50 centavos). The two varieties of One Peso commemorative had reported mintages of 10,000 pieces. They weigh 20 grams, and are 90% silver. Culion leper colony coinage The Culion leper colony was established in May 1906 by the Insular Government of the Philippine Islands in Culion Island, Palawan. It was modeled after the Kalaupapa Leprosy Settlement in Molokai, Hawaii. It was issued its own Special Culion Currency due to the erroneous belief that leprosy could be transmitted via handling of money. Only inmates of the colony were allowed to use what was commonly known as "leper money." It was prohibited for inmates to use regular Philippine currency, and it was prohibited for non-lepers to use the Culion currency. The first and
