Description
A striking large-format French 50 Francs coin featuring the iconic 'Hercules' design. While the 1977 issue was originally struck in 90% silver, this specific example has been aftermarket gold-plated (gilt) to enhance its visual appeal for use as a decorative piece or pendant. The reverse features the value and date within a laurel and oak wreath.
Key Features
Hercules design by Dupré, large 41mm diameter, 'REPUBLIQUE FRANÇAISE' inscription, and the 1977 date. The gold-plating is the defining (and non-original) characteristic.
Color & Finish
Yellow gold tone with a slightly dull, warm patina. The surface shows a semi-matte to satin finish likely caused by the plating process over the original silver luster.
Hallmarks & Stamps
REPUBLIQUE FRANÇAISE (Obverse text), 50 FRANCS 1977 (Reverse), Cornucopia mint mark (Paris), and Dolphin privy mark (Rousseau). No gold hallmarks as it is plated.
Dimensions Estimate
Diameter: 41 mm; Thickness: 2.7 mm (Large Crown size).
Gemstones & Inlays
None. Standard struck numismatic design.
Clasp & Closure
Reeded edge (milled). No jewelry clasp.
Chain & Links
Not applicable; reeded coin edge with vertical serrations for security and aesthetics.
Craftsmanship Details
High-quality industrial minting. The plating is likely electrolytic. Sharp details remain visible in the wreath and lettering despite the additive layer.
Authentication Indicators
Correct font style and spacing for the 1977 Paris Mint issue; visible cornucopia and dolphin marks. The yellowish hue is a diagnostic red flag for a silver coin, indicating plating.
Origin & Maker
Monnaie de Paris (Paris Mint), France.
Era & Period
Fifth Republic (Modern Era), dated 1977. Design by Augustin Dupré (originally 1795).
Age Estimate
Dated 1977 (46+ years old).
Cultural Significance
Represents the stability of the French Fifth Republic. The Hercules motif symbolizes the union of Liberty and Equality under the strength of the French people.
Condition Notes
Very Good (VF/XF details). Minor surface abrasions and light circular wear consistent with being handled. The plating appears intact but slightly oxidized.
Value Estimate
Primarily based on its 30g silver content (~$25-$35 USD depending on spot price). The gold plating does not add value and may slightly decrease numismatic value to pure coin collectors.
Care & Maintenance
Do not clean with silver polish as it will strip the thin gold plating. Use a soft lint-free cloth. Store in an airtight capsule to prevent the silver underneath from tarnishing through the gold.
