Drachm

The Drachm from Istros (Moesia) was used as a form of currency in the ancient Greek city of Istros, which is now modern-day Istanbul, Turkey. The coin was made of silver and weighed 4.75 grams, which was a significant amount for a coin at that time. The coin's design featured the image of a mythical creature called the Gorgoneion, which was a symbol of protection and power in ancient Greek mythology. The Gorgoneion was depicted as a woman's head with snakes for hair and a fierce expression, and it was believed to have the power to turn people to stone with a single glance. The use of the Gorgoneion on the coin was likely meant to convey the power and authority of the city of Istros.
