Pilipino Series
The Pilipino Series banknotes is the name used to refer to Philippine banknotes and coins issued by the Central Bank of the Philippines from 1969 to 1973, during the term of President Ferdinand Marcos. It was succeeded by the Ang Bagong Lipunan Series of banknotes, to which it shared a similar design. The lowest denomination of the series is 1-piso and the highest is 100-piso. This series represented a radical change from the English series. The bills underwent Filipinization and a design change. After the declaration of Proclamation № 1081 on September 23, 1972, the Central  Bank demonetized all the existing banknotes (both the English and Pilipino series) on March 1, 1974, pursuant to Presidential Decree No. 378. All of the unissued banknotes were sent back to the De La Rue plant in London for overprinting the watermark area with the words "ANG BAGONG LIPUNAN" and an oval geometric safety design.
