AI Appraisal Estimate

This is a French 20 Centimes coin, commonly referred to as the 'Marianne' type, designed by Henri Lagriffoul. The coin is composed of aluminum-bronze, giving it a distinct golden-yellow brassy hue. On the obverse, it features the left-facing profile of Marianne, the national personification of the French Republic, wearing a Phrygian cap adorned with a cockade. The inscription 'REPUBLIQUE FRANÇAISE' arcs around the top edge, and the designer's signature 'LAGRIFFOUL' is visible below the neck profile. The coin measures approximately 23.5mm in diameter with a smooth edge. This specific specimen shows signs of moderate circulation, with visible surface wear on the high points of Marianne's hair and cheek. There is a noticeable patina developing, particularly in the recessed areas of the lettering, and several small contact marks or 'bag marks' across the field. This design was primarily minted between 1962 and 2001, representing the Fifth Republic era of French currency before the adoption of the Euro. The craftsmanship reflects the industrial precision of the Monnaie de Paris, with sharp, clear typography and a balanced, neo-classical aesthetic typical of mid-20th-century European coinage.

I have conducted a visual examination of this French 20 Centimes coin (Marianne type). The specimen exhibits characteristics consistent with aluminum-bronze issues minted by the Monnaie de Paris during the Fifth Republic. Based on the provided description of surface wear on the high points of Marianne’s hair and the presence of contact marks, I categorize this coin in 'Very Fine' to 'Extra Fine' circulated condition. Authenticity appears consistent with circulating coinage of the era; the sharp typography and specific patina in the recesses are typical of the Lagriffoul design. From a market perspective, these coins were produced in massive quantities—often hundreds of millions per year—making them extremely common in the numismatic trade. While they hold historical value as a symbol of pre-Euro French currency, they carry very little premium above their metal value unless they are in ‘Mint State’ (MS) condition or represent a rare key date (such as 1962 with four folds in the hair or the 1990s proofs). Comparables for circulated specimens typically sell in bulk lots or for minimal amounts in 'pick bins' at coin shops. Factors limiting value include the moderate circulation wear and the lack of a specific rare date or error. Please note that this appraisal is based on photographic evidence alone. A physical inspection would be required to verify weight, exact diameter, and metallic composition to rule out contemporary counterfeits. Scientific testing (XRF) and high-magnification microscopy would be necessary to confirm the absence of 'tooling' or cleaning, which can further decrease value. No provenance documentation was provided, though it is rarely required for such high-mintage modern issues.
