A coin with some oxides, a capsule (please, check photos).
The Cook Islands 5 Dollars “Archimedes – 1850” silver proof coin, issued in 1999, celebrates maritime engineering and the legacy of Archimedes, whose principles of buoyancy laid the foundation for shipbuilding science. This elegant commemorative piece unites classical knowledge with the romance of 19th-century seafaring.
The reverse depicts a majestic clipper ship under full sail, cutting through stylized ocean waves. Fine engraved details highlight the towering masts, rigging lines, furled and unfurled sails, flags flying atop spars, and the long, sleek hull gliding across textured water. The inscription “ARCHIMEDES • 1850” arches above, while “5 DOLLARS” appears below, framing the maritime scene. The mirror-like proof field contrasts beautifully with frosted relief, enhancing the ship’s silhouette and movement.
The obverse features the crowned effigy of Queen Elizabeth II, with inscriptions “ELIZABETH II,” “COOK ISLANDS,” and the year 1999. Struck in fine silver in proof quality, this coin is a refined tribute to nautical history, scientific discovery, and global exploration. A superb collectible for enthusiasts of ships, navigation, and world numismatics.
