Description
A gold-colored coin featuring the iconic Marianne portrait by Jules-Clément Chaplain. The obverse depicts the personification of the French Republic in profile. While the design matches the famous 'Marianne Rooster' 20 Francs, the significant surface corrosion and lack of metallic luster suggest this is not solid gold bullion.
Key Features
High-relief Marianne portrait, Phrygian cap icon, oak leaf wreath, and distinct serif typography typical of French coinage.
Color & Finish
Dull brassy yellow with heavy brownish-green oxidation/patina; matte and porous surface.
Hallmarks & Stamps
Text 'REPUBLIQUE FRANÇAISE' on obverse; engraver mark 'J.C. CHAPLAIN' visible behind the neck.
Dimensions Estimate
Standard 21 mm diameter and 1.25 mm thickness.
Gemstones & Inlays
None; relief portrait of Marianne wearing a Phrygian cap and oak leaf wreath.
Clasp & Closure
Reeded (milled) edge characteristic of French circulation coinage (not visible but standard for type).
Chain & Links
Round planchet construction; raised rim for protection against wear.
Craftsmanship Details
Originals are precision die-struck; this specimen exhibits signs of mold casting or inferior plating techniques.
Authentication Indicators
Red flags: The greenish oxidation and brown spotting are inconsistent with 90% gold purity. The surface texture appears cast rather than struck.
Origin & Maker
Monnaie de Paris (Paris Mint) for originals; this specimen shows signs of unofficial manufacture.
Era & Period
Belle Époque / Third Republic (Design originally 1899-1914).
Age Estimate
Design era 1899-1914; physical specimen appears to be a late 20th-century replica based on surface decay.
Cultural Significance
Marianne is the national personification of the French Republic, symbolizing liberty, equality, and fraternity.
Condition Notes
Poor to Fair (NF - Net Fine); significant pitting, surface corrosion, and discoloration. Evidence of 'greening' suggests copper-based substrate.
Value Estimate
Melt value of base metal ($0.05) if counterfeit; approximately $400-$450 USD if proven as authentic 21.6K gold.
Care & Maintenance
Do not clean with abrasives; use a soft cloth. If base metal, store in dry conditions to prevent further oxidation.
