Napoleon III silver Proof Uniface Reverse Essai Franc 1862 PR67 NGC, cf. Maz-1671 (there, both sides struck). Plain edge. Absolute eye-candy and almost assuredly as close to perfect as one is apt to find, the surfaces deep wells of watery white luster crossed only by thin ranks of die polish lines. An already rare essai, a double-sided example of which in SP65 achieved the equivalent of $4500 in a MDC Monnaies de Collection sarl sale (Auction 3, 1 December 2017, lot 912). From the Engelen Collection of World Coinage
