During the Japanese occupation there was a very active resistance movement in the Philippines and allied inteligence was very much aware, of the economic situation in the islands, and the need to bring new coins and currency with them when they liberated the Philippines.
In preparation for General MacArthur's return to the Philippines the Treasury Department ordered the Philadelphia, and San Francisco Mints to strike millions of Five Centavos coins. The Philadelphia Mint struck 21,198,000 Five Centavos dated 1944. There is no Mint Mark on the coins struck at Philadelphia. The San Francisco Mint Struck 14,040,000 Five Centavos dated 1944 and 72,796,000 dated 1945. Coins struck at San Francisco have a S Mint Mark.
When American forces liberated the Philippines in 1944 - 1945 they brought with them the Wartime Alloy Victory Coins produced in the continental United States.
