Thomas De La Rue has printed Peruvian currency for decades, and this 2019 issue continues that relationship. The Banco Central de Reserva del Perú has maintained a notably conservative approach to its cotton paper series even as many regional central banks migrated to polymer — a deliberate policy choice given Peru's humidity gradients across coastal, Andean, and Amazonian circulation zones, where polymer notes can perform unpredictably.

The security package here — watermark and thread only — is modest relative to contemporaneous De La Rue output for other clients, suggesting this denomination sits in a tier the BCR considers low enough risk to warrant lighter specification.
