10 Sucres

Banco del Pichincha was founded in Quito in 1906 and became one of several regional Ecuadorian banks authorized to issue their own currency under the country's decentralized banking regime — a system that persisted until the 1927 Kemmerer Mission reforms forced consolidation and stripped private banks of note-issuing rights entirely. This note falls within that last window of legitimate private emission.

The American Bank Note Company's involvement was practically obligatory for Ecuadorian issuers of the period; ABNC held near-monopoly relationships with most South American banks requiring security printing, and plate elements were frequently shared or adapted across clients. Whether this specific design was exclusive to Pichincha or borrowed from a common stock plate is worth examining before attribution.
