Final answer:
The idea that currency has always been a part of human economic systems is incorrect. Originally, goods and services were exchanged through bartering or as gifts, which eventually led to the creation of money as an agreed-upon means of exchange. Coinage began in Lydia around 650-600 B.C.E., with money taking various forms throughout history.
Step-by-step explanation:
The statement that currency (coin, cash) has always been a part of human economic systems is false. Initially, most goods and services were traded through gifts or bartering in small social groups. To facilitate trade and solve the problems of bartering, various societies developed the concept of money, which is an object that a society agrees to assign a value to, allowing it to be exchanged for payment at any time.
Money has taken many forms, such as cowry shells, rice, barley, or rum, evolving with time. Later, precious metals like gold and silver became the preferred means due to their durability and portability. The first coins were minted in Lydia around 650-600 B.C.E., laying the foundation for a standardized monetary system. Legal codes were even established to regulate money's value and its exchange. Today, money has continued to evolve, manifesting not only in physical forms but also in digital transactions, maintaining its essence as a medium for commerce.
