Indian coins typically feature symbols or images specific to Indian culture, history, or religious beliefs, while Greek coins often depict mythological figures, gods, or scenes from Greek mythology. Indian coins may also include inscriptions in regional languages, while Greek coins usually have inscriptions in ancient Greek. Additionally, Indian coins were traditionally made of gold, silver, or copper, while Greek coins were commonly made of silver or bronze.
