Mexico 1 Peso Banknote (Series AA, dated 1945)

This is a historical 1 Peso banknote issued by the Banco de Mexico, specifically identification series AA, featuring a prominent date of 22-XII-45. The note is characterized by its vertical orientation and intricate green, tan, and red ink engravings. The central design element is the highly detailed Aztec Sun Stone (Calendar Stone), flanked by two decorative vignettes containing the denomination '1'. The text 'BANCO DE MEXICO' is printed along the right margin. This example bears the red serial number E211591. In terms of condition, the note is in heavily circulated, 'Fair' to 'About Good' grade. There is significant structural wear, including multiple deep vertical and horizontal folds, several small tears along the margins (most notably on the right edge), and rounded, fraying corners. The paper shows heavy overall foxing, staining, and surface soiling leading to a darkened patina. The signatures of the bank officials are visible but slightly faded. This type of note was manufactured by the American Bank Note Company (ABNC) for Mexico, a hallmarks of which is the high-quality fine-line intaglio printing that remains partially crisp despite the heavy wear. It represents a significant era of mid-20th-century Mexican currency design before the bank transitioned to domestic production.
