Greek coins were among the first standardized forms of currency in the ancient world, emerging around the 7th century BCE. Made from precious metals like silver and gold, these coins featured images of gods, goddesses, and symbols that represented different city-states, such as Athens and Sparta. The use of coins facilitated trade and commerce, allowing people to buy and sell goods more easily. The design and weight of Greek coins varied by region, reflecting local culture and economy. The Athenian silver drachma became particularly famous and widely used, influencing later coinage in the Mediterranean. Greek coins played a crucial role in the development of economic systems and trade networks throughout ancient Greece.
