Ferdinand I as Prince copper Essai 10 Santim 1887-AB MS64 Red and Brown NGC, KM-E3. Attractive mahogany color beautifully accentuates this pattern's well-struck features and instances of coppery luster effortlessly shimmer upon rotation. Designed by Auguste Birchaut, this Essai has a purported mintage of 8 pieces, which further adds to its scarcity. Highly appealing and choice.
Estimate: 2500-3500 USD
