The Meaning of Money
Prior to the creation of money, individuals and firms had to accept other goods or services as payment, or be self-sufficient by producing everything required
Often lacking self-sufficiency or driven by the desire for a wider range of goods/services, bartering became the norm but it too had problems
As individuals and firms trade with each other in order to acquire goods or raw materials, they require a means of exchange that is acceptable and easy to use
Modern currency fulfils this purpose and money functions as a medium of exchange, a measure of value, a store of value, and a method of deferred payment
The Functions of Money

The Characteristics of Money
Many items were used for centuries as a form of money such as gold, silver, shells, beer, tobacco
However, each one of these items had some characteristics that made the less than ideal for exchange in certain circumstances
Good money has a number of essential characteristics - and modern currency fulfils them all
Divisibility: to be a valued medium of exchange, currency must be divisible. €50 notes can be exchanged for €10 euro notes or €1 coins
Acceptability: the currency must be valued and widely accepted by society as a valid way to pay for goods/services
Durability: the currency must be robust, not easily defaced/destroyed and last for a long period of time
Scarcity: the supply of the currency should be such that remains desirable and retains its value in the market. Oversupply would decrease its worth
Uniformity: in order to be a valid measure of value each denomination must be exactly the same e.g. every $50 note must be exactly the same
Portability: good currency is easy to carry/conceal
