Currency - Navo

• A currency in the most specific use of the word refers to money in any form when in actual use or circulation as a medium of exchange, especially circulating banknotes and coins.
• A definition of intermediate generality is that a currency is a system of money (monetary units) in common use, especially in a nation.
• Currency evolved from two basic innovations, both of which had occurred by 2000 BC.
• Originally money was a form of receipt, representing grain stored in temple granaries in Summer in ancient Mesopotamia, then Ancient Egypt.
• In premodern China, the need for credit and for a medium of exchange that was less physically cumbersome than large numbers of copper coins led to the introduction of paper money.
