1948 Banco de México 1 Peso Banknote

This is a Mexican 1 Peso banknote issued by the Banco de México, dated '22-XII-48' (December 22, 1948). The bill features an intricate design focused on the Aztec Sun Stone (Piedra del Sol) in the center, flanked by stylized '1' numerals and the text 'UN PESO'. The note is printed in a dark ink, likely green or black, on paper that has significantly yellowed and darkened over time due to age and handling. Notable markings include the red serial number 'E211591' appearing twice, the series designation 'SERIE BD', and various signatures at the bottom. The condition of the piece is poor; it exhibits heavy biological staining, significant folding with a central vertical crease that has caused structural failure, and substantial paper loss at the upper left and right corners. The edges are frayed and uneven, indicating high circulation and improper storage. The craftsmanship reflects the mid-20th-century printing standards of the American Bank Note Company (which produced these for Mexico), showcasing fine line engraving and complex guilloche patterns intended to deter counterfeiting. Despite its historical interest, the severe physical degradation, including tears and missing fragments, significantly impacts its integrity as a numismatic specimen.

I have examined the digital representation of this 1948 Mexico 1 Peso banknote. This specific issue, Series BD, was printed by the American Bank Note Company and is a well-documented part of Mexico's numismatic history. Upon visual inspection, the note exhibits severe structural degradation, categorized as 'Poor' or 'About Good' (AG) at best. The central vertical crease has progressed to a full-split vulnerability, and significant paper loss is evident in the upper corners. Heavy foxing, biological staining, and frayed margins further compromise the specimen's integrity. From a market perspective, these notes were printed in high volume. While the 'Calendario Azteca' design remains iconic and highly collectible in 'Uncirculated' condition (where they may fetch $15-$30), the value for heavily circulated and damaged examples is negligible. Comparable specimens in this state are frequently found in bargain bins or sold as bulk curiosities. The demand for a 1948 Peso in this condition is limited to entry-level 'type' collectors or those seeking historical artifacts regardless of grade. Authenticity cannot be 100% verified via image alone. While the fine-line engraving and guilloche patterns appear consistent with ABNC standards, a physical inspection is required to verify the paper's watermark, fiber composition, and the presence of raised intaglio ink. Given the low market value, professional third-party grading (PMG/PCGS) is not financially recommended, as the cost of certification would exceed the value of the note. The valuation provided assumes the note is authentic but reflects its significant physical distress.
