AI Appraisal Estimate

This is a 100 Pesos circulating commemorative coin from Mexico, minted in 1985. The coin is composed of aluminum-bronze, giving it a distinct golden-yellow hue. On the obverse shown, it features the profile of Venustiano Carranza, a primary leader of the Mexican Revolution and the first president of the constitutionalist government. To the right of the portrait is the denomination '$100' oriented vertically, with the year '1985' below it. The mint mark 'Mo' for the Mexico City Mint is visible to the left. The name 'V. CARRANZA' is inscribed in small letters at the base of the portrait. The coin has a diameter of approximately 26.5mm and features a reeded edge. The condition appears to be 'Circulated' with visible surface wear, minor scratches, and accumulated grime within the recesses of the engraving, particularly around the beard and lettering. There is a slight patina developing, which is typical for bronze-based alloy coins of this age. The striking quality is standard for high-volume circulation currency of the mid-1980s period.

Upon visual examination of this 1985 Mexico 100 Pesos coin featuring Venustiano Carranza, I observe it to be a common example of circulating currency from the period. The aluminum-bronze alloy exhibits typical surface wear, mild oxidation, and minor contact marks consistent with a 'Fine' to 'Very Fine' circulated grade. The 'Mo' mint mark and relief details align with known specifications for the Casa de Moneda de México, and the patina suggests authentic age for this alloy. From a market perspective, this coin is exceptionally common. It was minted in massive quantities (over 186 million in 1985 alone) and was subsequently demonetized following the currency reform of 1993, which replaced these pesos with the 'Nuevo Peso' at a 1000:1 ratio. Consequently, it holds no legal tender status and its numismatic value is minimal. Similar specimens are frequently found in 'bargain bins' or sold in bulk by weight. There is currently no significant collector demand for this specific year and variety unless found in flawless, Mint State (MS65+) condition. While the visual characteristics strongly suggest authenticity, a definitive assessment is limited by the digital format. To fully authenticate this piece, I would require an in-person examination to verify its weight (approximately 11.97g), diameter (26.5mm), and non-magnetic properties. High-resolution edge inspection would be necessary to rule out contemporary counterfeits, though such forgeries are rare for this low-value denomination. No scientific testing or provenance documentation is typically pursued for this coin due to its high mintage and low market value.
