Switzerland
Confederation 2 Francs 1850-A, Paris mint, KM10, MS66 PCGS. A stunningly original jewel with sharply struck, essentially mark-free surfaces that present a pleasing mixture of blue, green and gold coloration on both sides. The first year of this type and not surprisingly, tied for the finest seen by both PCGS and NGC.
Estimate: 1500-2000 USD
