阅读下面短文,简要回答所给问题。

The first telephone cards, produced in 1976, were Italian. Five years later the first British card appeared, and now you can buy cards in more than a hundred countries. People usually start collecting cards because they are small and light and you do not need much space for them. It is also a cheap hobby for beginners, although for some people it becomes a serious business. In Paris, for example, there is a market where you can only buy telephone cards, and some cards cost up to £4,000. The first Japanese card has a value of about £28,000. Most people only see cards with prices like these in their collectors’ magazine.
