AUSTRIA. 100 Corona, 1908. Kremnitz Mint. NGC PROOF-61.Fr-514; KM-2812. Struck to commemorate the 60th anniversary of the reign of Franz Joseph I. A beautiful example with moderately frosty devices and strong reflectivity in the fields. Faint hairlines show under scrutiny but the surfaces remain remarkably attractive for this grade level. Virtually untoned with vibrant khaki-gold coloration.
