1 Sol 1/10 Libra Peruana de Oro

By 1918, Peru's banking system had fractured into competing private institutions unwilling to accept each other's notes at par. This piece is the product of a forced compromise: four rival banks — Banco del Perú y Londres, Italiano, Internacional del Perú, and Popular del Perú — were compelled by the government to issue a joint emergency fractional note to address a severe shortage of small-denomination currency that had been worsening since the outbreak of the First World War disrupted coin supplies.

The ABNC plate was shared across the consortium, with all four issuing banks named on the face — an arrangement without close parallel in Peruvian monetary history. The fractional designation itself, equating 1 Sol to 1/10 of a Libra Peruana de Oro, reflects the gold-linked accounting still nominally in force despite the practical suspension of specie payments.
