Philippine twenty-five-centavo coin
The twenty-five-sentimo coin (25¢) coin is the third-lowest denomination coin of the Philippine peso. During Spanish administration, coins valued at  a Spanish dollar (or peso) or two reales issued by Spain and Spanish America were generally accepted in the Philippines for 25 centimos. Following the 1864 release of the 20-centimo coin, however, a 25-centimo denomination was not issued until the end of the Spanish and American administrations. The first coin of the independent Philippines to be worth a quarter of a peso was issued in 1958 as twenty-five centavos (the name for the sub-unit under American rule). Its obverse featured a woman near a volcano. The denomination was written in English around its outside with the year at the bottom. On the reverse was the coat of arms of the Philippines and around it the inscription 'Central Bank of the Philippines'. The last issue of the coin was in 1966. History
