5 Pesos Fuertes

Banco de Cuyo operated out of Mendoza, the commercial hub of Argentina's western wine and mining corridor, and issued this note during the mid-to-late nineteenth century under the provincial banking regime that preceded federal monetary consolidation. The blank year field — printed as "18__" with the final digits completed in manuscript at issuance — is characteristic of how ABNC-produced plates were used across multiple years without requiring a new engraving contract.

The American Bank Note Company's involvement here is worth noting: ABNC held long-standing relationships with numerous Argentine provincial banks during this period, supplying security-printed stock that far exceeded local printing capabilities. PS1641 is scarce in any form; Banco de Cuyo's relatively short operating window and provincial reach meant limited initial circulation volumes.
