Franz Joseph I gold Proof 100 Corona 1908 PR63 NGC, Kremnitz mint, KM2812, Fr-514. An exceedingly popular issue struck to commemorate Franz Joseph's 60th year of reign, with arguably one of the most beautiful reverse design illustrations for the 20th century. The meticulously-rendered devices have managed to retain full crispness throughout, while the equally impressive, low-lying mirrors emit a soft glow that easily illuminates the surfaces. Visually engaging at every turn, and surpassed in technical quality by an elite few.
