1000 Piso Without horizontal bars

The abacá fiber component is not decorative policy — the Philippines is the world's dominant abacá producer, and its inclusion in the banknote substrate is a deliberate industrial decision, routing demand toward a domestically grown crop with deep roots in Mindanao and the Bicol region. Oberthur Fiduciaire's contract for this series was part of a broader BSP push toward European security printing standards after earlier domestic production runs drew criticism for inconsistent quality.

The "without horizontal bars" distinction refers to a security feature modification mid-series — a meaningful collector differentiator that the signature table alone cannot convey. The 2016A dates are particularly complex, appearing across three different signature combinations, making date-signature pairing essential for accurate attribution.
