14 mm diameter; very thin profile (standard for 19th-century 5 Franc gold coinage).

Clasp & Closure
Reeded edge for security and to prevent 'clipping' of the precious metal.

France; Paris Mint (indicated by the 'A' mint mark).

Second French Empire (Napoleonic Era, specifically 1852-1870).
Age Estimate

Cultural Significance
Represents the economic stability and imperial ambition of France under Napoleon III; part of the Latin Monetary Union standards.
Condition Notes
About Very Good (VG) to Fine (F). Significant circulation wear on high points of the crest, multiple surface scratches, and edge dings consistent with its age as circulating currency.
Value Estimate
$110 - $160 USD; value is derived from a mix of melt value (approx. $105) and a small numismatic premium due to its age and historical interest.
Care & Maintenance
Do not clean or polish; numismatic value is destroyed by abrasive cleaning. Store in a PVC-free plastic flip or archival capsule to prevent further scratching.
