France
Napoleon III gold 100 Francs 1868-BB AU55 NGC, Strasbourg mint, KM802.2. Mintage: 789. Lightly circulated with touch of friction evident atop Napoleon's cheek, brow and laureate bow, but otherwise typical contact atop the surfaces. The lowest mintage date from the entire Napoleon III 100 Francs series, and as such, a coin that seldom appears and is avidly sought.
