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 years of the Flora and Fauna Series which featured reduced sizes for all denominations. The Flora and Fauna Series was struck from 1983 through 1994.
