How can the terms barter and money economy be used to describe the change in the Lydian economy?

The Lydian economy transitioned from a barter system, where goods and services were exchanged directly, to a money economy characterized by the introduction of coinage. This shift facilitated more efficient trade by providing a standardized medium of exchange, reducing the complexities and limitations of barter. The use of coins allowed for greater ease in transactions and contributed to the growth of commerce and economic stability in Lydia. Ultimately, this transformation marked a significant advancement in economic practices, laying the groundwork for future monetary systems.
