Paris mint. KM-Pn100, Maz-2117 (R3). ESSAI edge. A rarely-seen representative, struck in double-weight, with one of the most covetable gold designs in all of French coinage. Featuring the emblematic rooster and personified liberty as Marianne and rendered in low relief, the slight cameo effect from gentle mirrors within the watery fields adding a surprising overall depth to the devices. Only a handful of comparable specimens have come to market in recent years and they have brought very spirited bidding leading to strong prices. A very rare and stunning piece that is sure to make any collection shine.
