 The Half Centavo proved useless in commerce and was withdrawn from circulation in 1904, and owing to a rise in silver prices the silver denominations (Ten centavos on up) were all reduced in size and alloy in 1907.In 1908, the San Francisco mint was finally authorized to coin base metal cents, and was thus positioned to take over all coinage production for the Philippines after that.After 1912 the Peso ceased to be minted.
