1948 Mexico 1 Peso Banknote (Banco de Mexico)

This is a one-peso banknote issued by the Banco de Mexico, dated December 22, 1948 (22-XII-48), specifically belonging to Series BD. The note features a central intricate graphic of the Aztec Calendar (Piedra del Sol), which is a signature element of this currency era. The primary color palette consists of a muted, aged cream or tan background with detailed green-to-grey engraved scrollwork and borders. The serial number 'E211591' is printed in a contrasting red ink in two locations. The note was printed by the American Bank Note Company, as indicated by the small text at the bottom. Regarding condition, this specimen is in poor to fair circulated condition. Notable defects include significant 'ragging' and loss of material along the left edge, heavy vertical and horizontal center creases, and rounded, feathered corners. There is visible surface soiling, heavy foxing (brown spotting), and general paper softening due to age and handling. The note retains its historical signatures but lacks the crispness of a collectible-grade uncirculated bill. The craftsmanship is typified by the high-quality intaglio printing of the mid-20th century, which allowed for microscopic detail in the border patterns and central sun stone engraving.

I have examined the digital representation of this 1948 Mexican one-peso banknote (Series BD). Based on my visual analysis, the note appears authentic, exhibiting the characteristic intaglio printing of the American Bank Note Company, including the sharp geometric borders and the iconic Aztec Sun Stone central motif. However, the condition of this specimen is graded as 'Fair' to 'About Good.' I observed severe structural issues: significant loss of paper on the left margin, heavy horizontal and vertical creasing that has broken the surface fibers, and widespread foxing and environmental soiling. In the numismatic market, these notes were printed in massive quantities, making them very common. While the 1948 date is historically interesting, the value of this specific note is severely diminished by its poor physical state. High-grade (Uncirculated) examples of this series typically sell for $15-$25, whereas circulated examples like this one possess primarily sentimental or historical curiosity value. Limitations of this appraisal include the inability to verify paper texture, opacity, or the presence of microscopic hallmarks through an image. A definitive authentication would require a physical inspection to check for watermark consistency and paper weight. No further scientific testing or provenance is required for an item of this market value, as the cost of professional grading would far exceed the note's worth.
