Kyzikos was an ancient city located on the coast of Marmara Sea in present-day Turkey. It was known for its strategic position and thriving trade, which led to the minting of its own coins. The coins, often made of silver, featured various designs, including images of local deities and symbols representing the city. The Kyzikos coins are significant for collectors and historians, as they provide insight into the economic and cultural practices of the region during antiquity. These coins often bear inscriptions in Greek, reflecting the influence of Hellenistic culture in the area.
