From the Greek Black Sea colony of Olbia which provided slaves, cereal and fish. Before die struck coinage, these dolphin figures served as a means of exchange, vital for commerce to thrive. They are modeled as the bottlenose dolphins of the Black Sea which were both friendly and considered auspicious and sacred to Apollo. The dolphins are bronze, evidently hand-modeled as they vary considerably though always in leaping or breaching posture. This example is just over 1” long of slender form with a prominent eye on one side and dorsal fin. It has been professionally refurbished, silver plated on modern Sterling silver neck chain. Gift boxed with certificate of authenticity.
