Mexican Peso Banknote Appraisal

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.
