100 Pesos Treasury Certificate

Treasury Certificates were introduced in the Philippines under American administration as a parallel currency to the silver peso, backed by the peso's silver reserve rather than by direct coin redemption. The 1918 series coincides with wartime disruptions to silver supply and shipping, which created real pressure on the Philippine Treasury's ability to maintain specie backing — though the certificates themselves continued to circulate without public incident.

Two signature combinations exist for this pick number, reflecting successive Insular Treasurer appointments. The Harrison & Carmona pairing is the scarcer of the two. BEP production means the intaglio work is sharp, but these saw genuine tropical circulation, and paper degradation is a documented issue with surviving examples.
