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 money? What makes a ten-fen stamp worth ten fen？
When you buy a stamp, you also buy service from the post office. You get the letter sent by post. After the stamp has a postmark(邮戳), 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 of them are hard to find. To get one of these uncommon stamps, some collectors are willing to pay a great deal of money. They think it is worth much money.
