In modern society，people use money every day.It seems that it is very important in our life.That's because without money you can't buy any goods (商品) you want.But I think few people know the history of money.
Long ago，people did not need money.They lived on wild animals，fruits and other plants.As time passed，people learned to raise animals and crops.Sometimes，families produced more than they needed，so they started to trade with other families.Later，people began to use money as a means of exchange.However，it was not the kind of money we use today.They used shells，rice，salt，large stones，etc.
During the 600s BC，people began using coins as money.They soon found that coins were easier to carry than goods and lasted a long time.Later，countries began to make their own coins.
