How did the greek use of coinage increase trade?

The Greek use of coinage standardized currency, which simplified transactions and reduced the complexities associated with barter systems. Coins facilitated trade by providing a universally accepted medium of exchange, making it easier for merchants to conduct business across regions. This increased economic interactions and encouraged the growth of markets, leading to a flourishing trade network throughout the Greek world and beyond. Additionally, the ability to easily measure value in coins promoted trust and efficiency in trade practices.
