The New BSP Series
Until 1997, legal tender Philippine Coins consisted of 25 different designs from the English Series to the Improved Flora and Fauna Series. In response to public clamor for simplification, the Bangko Sentral ng Pilipinas issued BSP Circular No. 81 which called for the demonetization of all existing Central Bank coins in circulation. Effective January 2, 1997, only the New BSP coin series was deemed legal tender. In 2000, The 10-Peso coin was introduced, the first bi-metallic coin in Philippine history.
