Ang Bagong Lipunan Series

The Ang Bagong Lipunan Series (literally, ”The New Society Series") is the name used to refer to Philippine banknotes and coins issued by the Central Bank of the Philippines from 1973 to 1985. It was succeeded by the New Design series of banknotes. The lowest denomination of the series is 2-piso and the highest is 100-piso.

Background
After the declaration of martial law by President Ferdinand Marcos on September 23, 1972, the Central Bank was to demonetize the existing banknotes in 1974, pursuant to Presidential Decree 378. All the unissued Pilipino Series banknotes (except the one peso banknote) 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. The one peso note was replaced with the two peso note, which features the same elements of the demonetized "Pilipino" series one peso note.

On September 7, 1978, the Security Printing Plant in Quezon City was inaugurated to produce banknotes inside the country. Alongside the opening of its printing facilities, the seal of the Bangko Sentral ng Pilipinas was given minor changes.

The banknotes were still legal tender even after the introduction of the New Design Series banknotes, however, it was seldom used after the EDSA Revolution. The banknotes were eventually demonetized on February 2, 1993 (but were still exchangable with legal tender currency to the Central Bank until February 2, 1996) after clamors that the banknotes may have been used to buy votes for the 1992 Presidential Elections.
