Napoleon III gold 50 Francs 1867-BB MS63 NGC, Strasbourg mint, KM804.2, Fr-583. A select example with handsome russet patination that has gathered around the devices and a powerful portrait of the King which is the immediate focal point. As the grade suggests, the surfaces are lightly abraded, but all marks are within the confines of the designated grade.
