Introduction
Money is a fascinating subject and full of curiosities. It is important to capture this element for the students. The history of money and how various forms were used at different times is an interesting story. Modern forms of money are linked to the banking system. Money is a fundamental discovery, which has eased the day to day transactions, valuing goods and services and has allowed us to store the wealth and trade in future. "Money is anything which is widely accepted in payment for goods or in discharge of other business obligations" Robertson.
Evolution of Money
The word Money is derived from Roman word "Moneta Juno". It is the roman goddesses and the republic money of roman empire. The Indian rupee is derived from Sanskrit word 'Rupya' which means silver coin. Today we use paper notes, coins as money. But the evolution of this stage has not happened overnight. It took thousands of years to reach such a stage. There are many stages of evolution of money. The earliest and primitive stage is Barter system.
Barter system
Barter system is exchanging goods for goods without the use of money in the primitive stage. A barter system is an old method of exchange. This system has been used for centuries and long before money was invented. People exchanged services and goods for other services and goods in return. The value of bartering items can be negotiated with the other party. Bartering doesn't involve money which is one of the advantages. Hence Barter system had many deficiencies like,
1. Lack of double coincidence of wants,
2. Common measure of value
3. Indivisibility of commodities
4. Difficulties of storing wealth
Major stages of Evolution of Money
Commodity Money, Metallic Money, Paper Money, Credit Money or Bank Money, Near Money and recent forms of Money. Money has evolved through different stages according to the time, place and circumstances.
Commodity Money
In the earliest period of human civilization, any commodity that was generally demanded and chosen by common consent was used as money. Goods like furs, skins, salt, rice, wheat, utensils, weapons etc. were commonly used as money. Such exchange of goods for goods was known as 'Barter Exchange'.
Metallic Money
With progress of human civilization, commodity money changed into metallic money. Metals like gold, silver, copper, etc. were used as they could be easily handled and their quantity can be easily ascertained. It was the main form of money throughout the major portion of recorded history.
History of Metallic Money
The precious metals especially gold, silver, bronze were used for metallic money. The standard weight and fineness of metal particularly gold and silver with a seal on it became medium of exchange. They were of different denomination easily divisible, portable and were convenient in making payment. King Midas of Lydia innovated metal coin in the 8th century BC (BCE) by the ancient historian Herodotus. But gold coins were in use in india many centuries than in Lydia. The earliest issuers of coins in the world are the ancient Indians along with Chinese and lydians from the middle east. The first time Indian coins were minted in the 6th century BC (BCE) by the Mahajanpadas known as Puranas, Karshapanas or Panas. The Mauryas came up with the Punch Marked Coins minting of silver, gold copper or lead and Indo-Greek Kushan kings introduced the Greek custom of engraving portraits on the coins. Turkish sultans of Delhi has replaced the royal designs of Indian kings with Islamic Calligraphy by the 12th century AD (CE). The currency was made up of gold, silver and copper known as Tanka and lower valued coin known as Jittals. The Mugual Empire from 1526 AD (CE) consolidate the monetary system for the entire empire. In this era evolution of rupee occurred with Sher Shah Suri defeated Humayun and issued a silver coin of 178 gms known as rupiya and was divided into 40 copper pieces or paisa and during the whole Mugual period silver coin remained in use. During the British East India company i.e. 1600, the mughal currency remained popular but in 1717 AD (CE), Farrukhsiyar the Mughal Emperor gave permission to the Britishes to coin Mughal Money at the Bombay mint. The British gold coins were termed as Carolina, the silver coins as Angelina, the copper coins as cupperoon and the tin coins as tinny
Paper Money
It was found inconvenient as well as dangerous to carry gold and silver coins from place to place. So, invention of paper money marked a very important stage in the development of money. The development of paper money started on the basis of storage of gold and the receipts were issued by the goldsmiths for these storages. These receipts of goldsmiths were a substitute for money and became paper money. Paper money is regulated and controlled by Central Bank of the country. In India, printing, regulating, controlling the paper currencies are done by the Reserve Bank of India (RBI) which was established in 1935. At present, a very large part of money consists mainly of currency notes or paper money issued by the Reserve Bank of India.

Credit Money or Bank Money
Emergence of credit money took place almost side by side with that of paper money. People keep a part of their cash as deposits with banks, which they can withdraw at their convenience through cheques. The cheque (known as credit money or bank money), itself, is not money, but it performs the same as functions of money.
Near Money
The final stage in the evolution of money has been the use of bills of exchange, treasury bills, bonds, debentures, savings certificate etc.

Value of Money
Value of money is meant the purchasing power of money over goods and services in a country. Thus it is related to the price level of goods and services. But the relation between the value of money and price level is an inverse one.
Do You Know?
Symbol of Rupee: The Indian Rupee symbol designed by Mister Udayakumar, Villupuram Dist Tamil Nadu. It was approved by the Government of India on 15 July 2010.

ACTIVITY 3
Students to know about the value of money, Set up your classroom like a shop or market Students are asked to purchase some commodities from the shop Do the market activities Teacher and students together discuss the value of money
Nature of Money
There has been lot of controversy and confusion over the meaning and nature of money Scitovsky states that "Money is a difficult concept to define, partly because it fulfils not one but three functions, each of them providing a criterion of moneyness those of a unit of account, a medium of exchange, and a store of value". Sir John Hicks, says that "Money is defined by its functions, anything is money which is used as money, "Money is what money does". These are the functional definitions of money because they define money in terms of the functions it performs. Some economists define money in legal terms saying that "anything which state declares as money is money". Such money possesses general acceptability and has the legal power to discharge debts. But people may not accept legal money by refusing to sell goods and services against the payments of legal tender money.On the otherhand, they may accept some other things as money winch are not legally defined as money in discharge of debts. This may circulate freely.
Functions of Money
Functions of money are classified into Primary or Main functions, Secondary functions and Contingent functions.
Primary or main functions
The important functions of money performed in every economy are classified under main functions:
1) Medium of exchange or means of payment Money is used to buy the goods and services.
2) Measure of value The values of all the goods and services are expressed in terms of money. It is easier to determine the rate of exchange between various type of goods and services.
Secondary functions
The three important secondary functions are
1) Standard of deferred payment Money helps the future payments too. A borrower borrowing money today places himself under an obligation to pay a specified sum of money on some specified future date.
2) Store of value or store of purchasing power Savings were discouraged under barter system as some commodities are perishable. The introduction of money has helped to save it for future as it is not perishable.
3) Transfer of value or transfer of purchasing power Money makes the exchange of goods to distant places as well as abroad possible. It was therefore felt necessary to transfer purchasing power from one place to another.
Contingent functions
1. Basis of credit
2. Increase productivity of capital
3. Measurement and Distribution of National Income.
