second issues (1913 and 1920) were struck in aluminum by the Frank & Co. die establishment. All subsequent issues were minted by the newly reopened Manila Mint. The third issue (1922) was also aluminum, but the fourth, fifth, and sixth issues (1925, 1927, and 1930) were in copper-nickel alloy. The sixth issue was the final issue. In total, around 169,000 coins were struck for the Culion leper colony, between 1913 and 1930. By the 1920s, the segregation laws were relaxed. Non-leper settlers (locally known as sano) started coming into the island, mostly family members of the thousands of inmates who were forcibly relocated to the island during via the segregation program. However, exchange of money between the leper inmates and the non-leper settlers was still prohibited. In 1942, during the Japanese invasion of the Philippines in World War II, Culion was cut off from Manila, leading to a shortage of currency. The local Culion authorities issued an emergency currency printed on paper, with centavo denominations in pink paper and peso denominations in blue paper. The Japanese later attacked the island and destroyed its port, radio tower, and electricity generators, cutting off all supplies and contact to the island. This resulted in widespread starvation that resulted in 2,000 deaths. People who fled the island were also killed. It wasn't until 1945 that the US Army Air Corps was able to drop supplies on the island by parachute. After independence, the segregation law was revised to allow private home isolation and treatment, removing the need for a leper colony. By the 1980s, multi-drug therapies had reduced the status of leprosy to a treatable disease. In 2006, it was declared a leprosy-free area by the World Health Organization. The currency is discontinued but remains popular among coin collectors. After Philippine independence, 1946-1994 After the granting of independence to the Philippines in 1946, no coins were minted for the Philippine Republic until 1958, other than a small silver commemorative issue in 1947 to honor General Douglas MacArthur. A total of 200,000 50 centavos and 100,000 one peso coins were minted with the general's image on the obverse and the national coat-of-arms on the reverse. Struck at the San Francisco Mint, they carry the "S" mintmark below the date. In 1958, the 20 centavos was replaced with a 25 centavos and all coins were resized to be the same diameter as their US equivalents, albeit
