Philippine Coins: 1 PISO Ang Bagong Lipunan Series
In 1975, 3 years after the declaration of Martial Law by President Ferdinand Marcos, the Philippine coinage would once again be changed. This series is called “Ang Bagong Lipunan” (The New Society) or ABL series. This replaced the Pilipino series coins and was created to commemorate a new government.
This series is divided into 2 periods, 1975 to 1978, and 1979 to 1982. The 50 Sentimo was not included in this series and a new, 5 PISO, denomination was added. I will show you the differences between the coins of each period.
Featured here is the 1 PISO coin.
Weight: 9.5 g
Diameter: 29 mm
The PISO is different from the SENTIMO coins in this series because it does not feature the BSP logo on the reverse side. Instead, it features the seal of the Republic of The Philippines. If you will notice the digits of the year are divided by the seal – “19” on the left side of the seal, and “75” (0r whatever year from 75 to 82) on the right side.
During the 1975-1978 period, the PISO was still minted in US and Germany. Coins for succeeding years were minted locally and featured the BSP mint mark below the word “PISO” on the obverse except for proof coins from the Franklin Min in the US. Another notable difference from the coins from each period is the banner on the reverse side. Banner reads, “REPUBLIKA NG PILIPINAS” for the 1975 to 1978 coins. For the 1979 to 1982 period, the banner reads, “ISANG BANSA ISANG DIWA”.
Proof coins were minted at the Franklin Mint in the US, a private company. To distinguish the coins made at the Franklin Mint from other coins, a mint mark was added at the right side of the seal on the reverse. The mint mark looks like a stylized “f” where the horizontal bar curves downward making it look like the letters “F” and “M” were merged together. The BSP mint mark cannot be seen on coins from the Franklin Mint. A 1 PISO from 1979 to 1982 minted at the Franklin mint will feature the FM mint mark on the reverse, but not the BSP on the obverse.
You can see the FM mint mark below “75” right above where the banner ends.
The 1982 1 PISO has 2 types. The differences are not very apparent, but it can be concluded that the 1982 coins had different minting dies. The difference can be seen on the reverse side of the coin. Refer to table below.

This coin is no longer legal tender. It is readily available from all local coin dealers for a relatively low price. I got my coins from a local coin dealer.
