Description
A stunning and rare numismatic masterpiece, this 100 Francs gold Piedfort issue celebrates the core tenets of the French Republic: 'Liberté, Égalité, Fraternité'. Topped with a Phrygian cap (Liberty Cap), the stylized, interlocking typography creates a powerful architectural silhouette. As a Piedfort—meaning 'heavy foot'—this coin was struck on a planchet of double the standard thickness, making it a highly sought-after rarity among collectors of French gold.

Double thickness (Piedfort status), avant-garde typography, Liberty cap motif, and extremely low mintage (often under 500 pieces for gold Piedforts).

Value Estimate
$2,500 - $3,200 USD. Value is based on Gold Melt Value (~$2,300) plus a significant numismatic premium (approx 20-40%) due to its rarity as a Piedfort and its limited mintage.
Care & Maintenance
Handle only by the edges with lint-free gloves. Store in a PVC-free airtight capsule. Never use abrasive cleaners or polishes as they destroy the numismatic 'frost' and lower value.
