Most British telephone cards are just plain green, but card collecting is becoming a popular hobby in Britain and collectors even have their own magazine, International Telephone Cards. One reason for their interests is that cards from around the world come in a wide variety of different and often very attractive design. There are 100, 000 different cards in Japan alone, and there you can put your own design onto a bank card simply by using a photograph or a business card.

The first telephone cards, produced in 1976, were Italian. Five years later the first British telephone cards appeared, and now you can buy cards in more than a hundred countries. People usually start collecting cards because they are attractive, small and light, and they do not need much space. 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 buy only telephone cards, and some French cards cost up to 4,000 pounds. The first Japanese card has a value of about 28,000 pounds. Most people only see cards with prices like these in their collectors’ magazine.
