France
Napoleon III gold Proof Essai 5 Dollars - 25 Francs 1867 PR64 PCGS, Paris mint, KM-E29, Maz-1745 (R4). By Barre. Lively reflectivity exists in the fields and the surfaces are vividly toned, with evident frost atop Napoleon III's bust that results in an outstanding cameo-like appearance. Overall, a very choice example of this dual-denominated pattern from the "Essai Monetaire" series that was produced as part of the international currency test that was performed at the monetary conference in Paris in 1867.
Estimate: 12000-15000 USD
