Philippine Coins: 1 Sentimo 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 SENTIMO coin.
Weight: 1.22 g
Diameter: 19 mm
This is the only Philippine coin I know of that has this shape. While all coins before this series were all round, the shape of this coin is a rounded square. It was meant to aid the visually impaired in easily identifying the coin.
During the 1975-1978 period, the 1 SENTIMO was minted in the UK. On the second period, 1979-1982, the Bangko Sentral ng Pilipinas already had its own mint and coins from then on were minted locally.
From 1979 to 1982 the BSP mint mark can be seen on the obverse, right below “SENTIMO”. On the reverse, the original 1949 BSP logo was changed to the graphical rendering.
Personally, I think the coins from the first period (1975-1979) are better looking, especially the BSP logo on the reverse. The graphical rendering of the logo just meant the engraver was lazy. The logo is just ugly, to put it bluntly.
This coin is no longer legal tender. It is readily available from all local coin dealers for a relatively low price. I found mine in a forgotten bag of coins at home.
