Final answer:
The Ionians transmitted the invention of coinage from the Lydians to the Greek world in the sixth century BCE, transforming economic and trade activities significantly.
Step-by-step explanation:
The Ionians transmitted the Lydian invention of coinage to the Greek world. This occurred in the sixth century BCE where the Lydians had stamped pieces of silver with an image, a practice which was then adopted by Athens for their own currency. This innovation was momentous as it provided a simpler medium of exchange than bartering goods or weighing precious metals. This boosted économique activities in the agora (marketplace) of each city-state and stimulated economic growth, as currency made trade more accessible and efficient.
