500 Pesos

El Banco de Guatemala was a private commercial bank that held the concession to issue currency in Guatemala during the Liberal period — a familiar arrangement across Central America at the time, where note-issuing rights were granted rather than state-held. The Compañía Internacional de Billetes de Banco was the Spanish-language identity under which the American Bank Note Company marketed itself to Latin American clients, and the plates it produced for this series reflect that firm's characteristic high-intaglio quality.

The 500 Pesos denomination would have represented a significant sum in daily Guatemalan commerce, making this effectively a clearing instrument between institutions rather than a note seen in ordinary hands. Guatemala's transition to a state central bank — the Banco Central de Guatemala, established in 1926 — marks the close of this series' issue window and the end of private note-issuing concessions in the country.
