Ang Bagong Lipunan Series

Three years after Martial Law was declared, the Ang Bagong Lipunan Series was introduced to commemorate Ferdinand Marcos' "New Society" initiative. It was the first series not to feature the 50 Sentimos denomination. Significant changes to the coinage were made in 1979, when both the BSP seal and the coat of arms were changed, and domestic coin production began, with the BSP Security Plant Complex's minting machinery fully operational that year. The series was demonetized after January 2, 1998, as per BSP Circular No. 81, Series of 1995.
