In general, money is an object that the general public agrees as a medium of exchange in economic activity. The presence of money facilitates the sale and purchase of goods and services to be more effective and efficient. The value of money has also grown from being initially only a medium of exchange to being a measurement tool for driving transactions.
Based on history, the existence of money was first coined by the Lydians who lived in Turkey in the 6th century BC. The money is made of a mixture of gold and silver and is shaped like a pea. The ratio of the gold and silver content in the money is 75:25 and becomes the standard. They named the money electrum.
Coins were then first created in 560-546 BC by Croseus in Greece. In the history of money, the Greeks are known as the inventors of the first coins. The Greeks minted various types of coins whose value they determined based on the material from which they were made.
However, over time due to the limited raw material for coins (gold and silver), the Chinese people came up with the idea of making paper money in the 1st century AD. When referring to history, the manufacture of paper money actually started before the Tang Dynasty, but failed because it was difficult to find durable paper materials. It was only when the Tang Dynasty came to power, that someone named Ts'ai Lun succeeded in creating paper from mulberry bark.
