The Evolution of Currency: From Barter to Credit Money

Introduction

The development of currency has been a cornerstone of human economic activity, enabling the efficient exchange of goods and services across time and space. Historically, societies relied on barter systems, where direct exchanges of goods and services were the primary means of trade.
