1 peso 1957

Common. This is a regular issue from 1957 with substantial print quantities, evidenced by: (1) ready availability in the secondary market with multiple eBay sales records showing typical prices in the $1-5 range depending on condition; (2) catalog valuations from 2019 listing UNC examples at $4.50, indicating moderate collector interest but no scarcity premium; (3) the note's appearance in standard catalogs as a mainstream variant (P-59c) of a base Pick number with multiple documented variants, suggesting this was part of a larger, routine currency circulation. Most examples encountered are common-grade circulated pieces, making UNC examples somewhat more desirable but not rare.

Issued on December 4, 1957, this banknote reflects Mexico's post-revolutionary period when the nation was consolidating its identity through numismatic imagery. The Aztec calendar stone on the obverse celebrates pre-Columbian heritage and indigenous Mexican civilization, while the Independence Monument on the reverse commemorates Mexico's struggle for national independence. This note represents a transitional period in Mexican currency design, distinguished by the addition of 'MEXICO D.F.' to earlier designs, marking it as a variant of the P-56 issue.

The obverse features the Aztec Sun Stone (Piedra del Sol) as the central vignette, a circular carved stone disk representing the Aztec cosmological calendar with intricate symbolic details rendered in black. This design element was a staple of Mexican currency emphasizing national heritage. The reverse depicts the Monument to Independence (Monumento a la Independencia) located in Mexico City, a tall commemorative tower with a crowned Victory figure atop its ornamental base, rendered in the dominant pink/red color scheme. Both sides employ elaborate guilloche patterns, ornate geometric borders in all four corners with decorative cartouches, fine-line crosshatching, and classical banknote security elements typical of American Bank Note Company production. The color scheme combines black and pink/tan on the obverse with predominantly pink/red on the reverse, creating visual distinction between sides.

OBVERSE: 'BANCO DE MEXICO' (Bank of Mexico) — issuing authority; 'PAGARA A LA VISTA AL PORTADOR EN EFECTIVO' (Will pay to the bearer on demand in cash) — legal tender declaration; 'SERIE HB' (Series HB) — series designation; 'MEXICO D.F.' (Mexico City) — location identifier added to this variant; '4·XII·57' (December 4, 1957) — issue date in day-month-year format; 'AMERICAN BANK NOTE COMPANY' — printer attribution; 'CONSEJERO' (Counselor/Advisor), 'INTERVENTOR DE LA COMISION MONETARIA' (Comptroller of the Monetary Commission), 'CAJERO' (Cashier) — official titles and authorization stamps. REVERSE: 'BANCO DE MEXICO' (Bank of Mexico); 'UN PESO' (One Peso) — denomination; 'AMERICAN BANK NOTE COMPANY' — printer attribution.

Intaglio printing (engraving), the standard method for currency production by the American Bank Note Company during this period. Evidence includes the fine-line guilloche patterns, precise crosshatching throughout the design, sharp definition of the Aztec calendar stone details, ornate decorative scrollwork, and the crisp impression visible on security elements. The multi-color underprinting visible on the obverse and the layered color effects on the reverse are characteristic of advanced intaglio techniques combining multiple engraved plates.

This note is confirmed as Pick P-59c, a variant distinguished by the addition of 'MEXICO D.F.' above the date at lower left, differentiating it from the earlier P-56 design. The series designation 'HB' and printer attribution to ABNC (American Bank Note Company) are consistent with catalog specifications for P-59c. The issue date of December 4, 1957 (4·XII·57) matches the known issuance period. Based on PMG population data, P-59c is one of five cataloged variants for this base Pick number (others being P-59e, P-59j, P-59l, and P-59s), suggesting moderate production across variant types. The serial number observed (J807989) and series designation are consistent with documented circulation characteristics for this issue.
