These are real Ancient Greek dolphin coins!
Dating back to the 3rd-1st Century BCE, these bronze coins were struck in the ancient city of Olbia.
PRICE IS PER RANDOMLY-SELECTED COIN and they can be shipped worldwide. These ~1.25" coins come in a gem jar for easy and safe display.
While it is, obviously, unusual for coins to be produced in the shape of an animal, bottle-nosed dolphins were found in abundance near this Black Sea city.
They also held religious significance in Ancient Greek mythology, represented as the "Sacred Fish" Delphinus.
According to lore, a dolphin helped Poseidon locate his future queen Amphitrite, earning the dolphin a place in the heavens as the constellation Delphinus.
