Issued on June 9, 1965, this note was produced during a period of relative stability in Mexico following the Revolution, when the Banco de México was reinforcing national identity through numismatic imagery. The prominently featured Aztec calendar stone on the obverse connects the modern Mexican state to its pre-Columbian heritage, while the Independence Monument on the reverse celebrates Mexico's liberation from Spanish colonial rule, reflecting the nation's mid-century focus on cultural continuity and democratic sovereignty.
The obverse features a large, intricately engraved circular Aztec calendar stone (the 'Piedra del Sol') dominating the center, surrounded by symmetrical ornamental corner medallions with heraldic eagle designs and decorative scrollwork typical of ABNC's fine-line engraving style. The reverse displays the Monument to Independence (Monumento a la Independencia) — the iconic Angel of Independence column — as the central vignette, flanked by ornamental corner designs with floral and architectural motifs. The color scheme of light pink/beige on the front and rose/red on the back creates visual distinction between the two sides while maintaining the dignified aesthetic appropriate to Mexican national currency of the era.
Front side: 'BANCO DE MEXICO' (Bank of Mexico); 'MEXICO, D.F.' (Mexico City); '9-VI-1965' (June 9, 1965); 'SERIE' (Series); 'A LA VISTA AL PORTADOR EN EFECTIVO' (Payable to bearer on sight in cash); 'AMERICAN BANK NOTE COMPANY' (printer attribution); Serial number 'Y836583'. Back side: 'BANCO DE MEXICO' (Bank of Mexico); 'UN PESO' (One Peso); 'AMERICAN BANK NOTE COMPANY' (printer attribution); 'BENEMÉRITO DE HUAJUCATLÁN' (Meritorious [figure] of Huajucatlán).
Intaglio printing (fine-line engraving) by American Bank Note Company (ABNC), characterized by the intricate concentric patterns within the Aztec calendar stone, the complex ornamental borders, detailed monument vignette, and fine tonal gradations visible throughout both sides. The crisp, sharp printing and the multiple layers of anti-counterfeiting design elements (ornamental medallions, fine scrollwork, and detailed engraved patterns) are hallmarks of ABNC's mid-20th century security printing standards.
This specimen corresponds to Pick P-59i based on the ABNC printer attribution and the distinctive 'MEXICO D.F.' text placement noted in the reference catalog. The visual analysis confirms the light pink/beige multicolor underprint and red reverse characteristic of this variant. The serial number prefix 'Y' and series designation fall within the BCO-BCX range documented for this issue. Other documented ABNC variants (P-59c, P-59e, P-59j, P-59l) exist within the same Pick number, likely representing different printing blocks or signature combinations; this example's specific signatures and complete serial formatting would determine the precise sub-variety if cross-referenced against PMG population data.
