100 Piso

The Security Plant Complex has printed Philippine banknotes in-house since 1978, making the BSP one of relatively few central banks in Southeast Asia that controls its own currency production end-to-end. This 100 Piso belongs to a series that has seen rolling updates through the early 2020s, with subtle security and design revisions issued across consecutive year dates rather than discrete series breaks — which is why the Pick reference carries a "W" prefix denoting the polymer-adjacent transitional paperstock classification.

Watermark-only security on a note at this denomination is notably lean by current international standards.
