5 Pesos El Banco de Londres y Mexico

The Banco de Londres y México was the oldest chartered bank in Mexico, established in 1864 under a British commercial concession — effectively a foreign institution operating with quasi-central authority during the Porfiriato. Its notes circulated alongside those of dozens of state banks permitted under the 1897 Ley General de Instituciones de Crédito, which theoretically standardized Mexican private banking but in practice created a chaotic patchwork of regional paper.

ABNC produced the plates in New York over a span covering nearly a quarter century of issue — the long date range reflects successive authorizations rather than a single continuous print run. The bank was nationalized and wound down following the Huerta regime's forced consolidation of 1913, which abruptly ended note issuance for the entire series.
