Napoleon III gold 100 Francs 1867-BB MS64 NGC, Strasbourg mint, KM802.2. An elite survivor of the date, and currently the single finest coin certified by either NGC or PCGS, with glowing luster in the mark-free fields and central devices that remain absent of distracting marks. For accuracy's sake, a couple easily removable greenish flecks are observed on both sides, but result in no ill-effect to the surfaces.From The Baron Collection
