| A stamp is just a piece of paper with a picture and some words printed on one side and some glue on the other side. What makes one of these bits of paper worth any money at all? When you buy a stamp you also buy service from the post office. You get the letter sent by post. After the stamp has done its job, the post office says it is worthless. You must buy a new one for each letter you send. But people often pay money for stamps that have already been used. Stamp collectors have fun just trying to collect as many different kinds as possible. Certain kinds are hard to find. To get one of those uncommon stamps, some collectors are willing to pay a great deal of money. They think it is worth something and that gives it value. If you collect stamps because they are especially beautiful or show all kinds of animals, then those are the ones that have value to you. | ||||||||||||
