in more base metals, other than the centavo. The same seated man with anvil and volcano or standing liberty with anvil and volcano designs were retained for the obverses while the seal of the Central Bank of the Philippines dominated the reverse. These coins were minted by the Philadelphia Mint from 1958 through 1963, and then by the Royal Mint in England and the Vereinigte Deutsche Metallweke in West Germany in 1965 (dated 1964) and 1966. In view of all subsequent issues using the Tagalog language, this coinage is often referred to as the English Series since it uses the English language. The next series was introduced in 1967, introducing images of various Philippine national heroes, and the use of the Tagalog (or "Pilipino") language, hence being called the Pilipino Series. The sizes of the coins were reduced. These coins were struck by the various US mints, except for some 50 centavos pieces dated 1972 which were minted in Singapore, and a couple commemorative issues struck by the Sherritt Mint in Canada. In 1972 the one peso denomination was reintroduced. In commemoration of Fedinand Marcos' declaration of Martial Law (which he titled "Ang Bagong Lipunan," the new society), a new series of coinage was issued in 1975, referred to as the Ang Bagong Lipunan Series. The 50 sentimo was done away with as a denomination and a new 5 peso issue took its place. A variety of mints provided these coins, including the Royal Mint in England and the Vereinigte Deutsche Metallweke in West Germany, Philadelphia and San Francisco mints in the US, the Franklin Mint (a private mint also in the US), the Sherritt Mint in Canada, and finally the Philippine's own mint, once it was opened and able to produce coinage. From this point on, the Philippine Mint (Bangko Sentral Pilipinas, "BSP") produced nearly all Philippine coinage. After eight years, the Ang Bagong Lipunan series gave way to a new series titled the Flora and Fauna Series, in which the coins, in addition to featuring various Philippine national heroes as before, also began featuring various plant and animal life forms native to the Philippines. The 50 sentimo and 2 piso denominations were reintroduced, which latter had not been struck as a coin since the Spanish had struck it in gold. The 5 piso denomination was stopped, but resumed (in a new smaller size) concurrent to the final four
