P#133 spans nearly two decades, printed throughout by Thomas De La Rue in London — an arrangement that outlasted several Philippine administrations and persisted well into the post-independence consolidation of the central bank's note programme. De La Rue had been printing Philippine currency since the Commonwealth period, and the continuity of the contract through 1970 reflects both institutional inertia and the difficulty of developing domestic printing capacity.

The series is common in circulated grades but genuinely scarce in high uncirculated condition, owing to the note's heavy everyday use as the base denomination during a period of significant rural-to-urban economic activity.
