Type

Coin (Numismatic/Bullion Type)

Purity

Non-gold; appears to be silver-colored base metal or silver-plated with heavy oxidation/fake patina. Authentic French Hercules 100 Francs coins were minted in .900 Fine Silver, not gold.

Gold Type

None identified; item displays a metallic grey/silver hue with significant dark mottling and potentially a gold-toned spray or 'brassing' at the 3 o'clock position.

Weight

Estimated 15-20g based on dimensions, though if a brass/lead counterfeit, it will deviate from the official 15.0g standard of the genuine silver 100 Francs.

Description

This item is a reproduction of the famous French 'Hercules' group coin design by Augustin Dupré. It depicts Hercules standing center, uniting Liberty (left, holding a pike) and Equality (right, holding a level). Originally a silver denomination, this specific piece shows visual indicators of a base-metal cast, including soft details and uneven surface coloration not found on genuine minted bullion.

Key Features

Hercules motif, revolutionary French motto, Dupré signature, large planchet size.

Color & Finish

Dull silver-grey with heavy black/brown oxidation and pitting. Surface lacks the crisp luster of struck precious metal and displays a 'soapy' cast texture.

Hallmarks & Stamps

Text: 'LIBERTE EGALITE FRATERNITE'. Artist signature 'Dupré' in cursive script at the bottom. No visible purity stamps or mint marks in the provided image.

Dimensions Estimate

Approximated diameter of 31mm (standard for this French denomination).

Gemstones & Inlays

None.

Clasp & Closure

Reeded or smooth edge (standard coin edge).

Chain & Links

N/A

Craftsmanship Details

Low quality. The legends appear slightly rounded rather than sharp, and the field (background) is remarkably grainy, typical of low-budget casting.

Authentication Indicators

Red Flags: Blotchy, uneven surface texture suggests a cast rather than a die-struck strike; the coin type itself (100 Francs Hercules) was never minted in gold by the French government (only silver or rare platinum/gold trials exist, which this does not resemble).

Origin & Maker

Design origin: France (Monnaie de Paris). Current item origin: Likely a non-official modern reproduction or counterfeit.

Era & Period

Design based on the 1795 Augustin Dupré motif; the 100 Francs silver coin was produced during the Fifth Republic (1982-1986).

Age Estimate

Modern (post-1980s) reproduction based on the grainy surface texture and artificial-looking patina.

Cultural Significance

Represents the French republican values of Liberty, Equality, and Fraternity, personified through Greco-Roman symbolism.

Condition Notes

Poor to Fair. Surface shows heavy blotchy discoloration, potential 'pitting' from casting bubbles, and overall lack of detail in the hair and drapery.

Value Estimate

Minimal ($1 - $5) as a novelty/reproduction. This is not a gold item and shows significant signs of being a base-metal counterfeit of a silver coin.

Care & Maintenance

Do not clean with abrasives. If a reproduction, its value is purely decorative. Keep dry to prevent further base-metal oxidation.

Interesting Facts

The Hercules design is one of the most enduring in French numismatics, appearing on coins ranging from the late 18th century to modern commemorative Euros.
