TYPE Ancient Greece, Olbia (Sarmatia), ca. 180-170 BC, AE20 (bronze), 7.7g DESCRIPTION . Obv: Head of Demeter to right, uncertain weak countermark on face Rev: Sea-eagle standing on dolphin to left, Greek inscription BSE below REFERENCE: An 303-6 GRADING: VG / F+, dark brown-red patina ORDER INFO: G1041, $20 While hardly reflecting zoological reality - as an 18-pound eagle is unlikely to attack a much heavier dolphin at sea - the reverse scene, present on coinages of two Black Sea cities (Istros and Sinope - though rather distant, they were both originally Milesian colonies) might have some symbolic significance in juxtaposing two leading deities - Zeus and Poseidon - through their sacred animals.
