Today anyone will accept money in exchange for goods and services.. People use money tobuy food, furniture, books, bicycles and hundreds of others they need or want. When they work,they usually get paid in money.
Most of the money today is made of metal or paper. But people used to use all kinds of things as money. One of the first kinds of money was shells.
Shells were not the only things used as money. In China, cloth and knives were used. In thePhilippine Islands, rice was used as money. In some parts of Africa, cattle were one of the earliestkinds of money. Other animals were used as money, too.
The f&39;irst metal coins were made in China. They were round and had a square hole in the cen-tre. People strung them together and carried them from place to place.
Different countries have used different metals and designs for their money. The first coins inEngland were made of tin. Sweden and Russia used copper to make their money. Later, othercountries began to make coins of gold and silver.
But even gold and silver were inconvenient if you had to buy something expensive. Again the &39;Chinese thought of a way to improve money. They began to use paper money. The first papermoney looked more like a note from one person to another than paper money used today.
Money has had an interesting history from the days of sh~ll money until today.
