AI Appraisal Estimate

This is a circular decorative souvenir plate featuring the Aztec Calendar (Piedra del Sol/Sun Stone) as the central motif. Constructed from a polished metal, likely brass or a brass-plated base, it showcases vibrant kiln-fired or cold-enamel polychrome work in shades of emerald green, deep red, turquoise blue, and white. The plate is divided into distinct registers: a central medallion depicting the sun god Tonatiuh, followed by concentric rings containing various Nahuatl glyphs and symbols representing the 20 days of the Aztec month. The wide outer rim is finished in a saturated green enamel and decorated with stylized eagle and serpent figures, reflecting Pre-Columbian iconography. At the bottom of the rim, the word 'MEXICO' is prominently integrated into the design. The plate exhibits a high-gloss finish typical of mid-to-late 20th-century tourist ware. The craftsmanship indicates a commercial production intended for the gift and souvenir market, likely dating from the 1970s to the early 1990s. The surface appears to be in relatively good condition with no visible chipping to the enamel, though minor surface scratches and slight tarnishing on the exposed metallic segments are consistent with its age and use as a display piece.

I have completed a visual assessment of the Aztec Calendar decorative souvenir plate. This piece is a classic example of mid-to-late 20th-century Mexican tourist ware, likely produced between 1975 and 1990. The construction centers on a stamped brass or brass-plated substrate featuring a vibrant, multi-color enamel application. The condition is excellent for its age, with the polychrome enamel showing high gloss and no significant losses or 'flea bites.' The concentric rings of Nahuatl glyphs are clearly defined, though the commercial nature of the stamping indicates mass production rather than artisanal hand-tooling. Market demand for these items is moderate, primarily driven by interior decor trends and 'Mid-Century Modern' souvenir collecting. Comparables for similar 12-inch brass and enamel plates from this era typically sell within the $40 to $80 range at auction or via online vintage marketplaces. The 'MEXICO' lettering confirms its origin as an export or tourist commodity rather than a ritual or archaeological artifact. Limitations of this appraisal include the inability to verify the base metal composition or detect fine hairline cracks in the enamel via digital imagery. A physical inspection would be required to rule out lead-based pigments or confirm the presence of a maker's mark on the reverse, such as 'Hecho en Mexico' or a specific workshop stamp, which could slightly influence the floor price. No scientific testing is recommended given the item's established category as a 20th-century collectible.
