Take a guess. How much do you think an eight-side, red-brown stamp is worth? Well, it was sold by the Robert A. Siegel Galleries in New York City for $ 280,000!

　　The stamp is an 1856 one-cent British Guiana. It pictures an old sailing ship with words in Latin above and below it. You may think the stamp looks rather dull. But it is the only one of its kind in the world.

　　Any stamp collector would like to own the one-cent British Guiana. But you don't have to aim for value in a stamp collection. You may collect bright new stamps that cost very little. The idea is to pick a topic that interests you and then collect every stamp you can find that pictures it in some way. For years a Pennsylvania man looked for stamps showing roofs. Why? Well, the collector's name was John C. Ruhf.

　　President Roosevelt always found time to spend with his stamps. After his death, they were sold for over $ 25,000. No one will even try to put a value on the world's greatest collections. They are those of the British Museum, the U.S. Post Office and the British Royal Family. It is said that the Royal Family owns every stamp ever put out by Great Britain since 1840. No, that's not quite right. There's one stamp missing.

　　Stamp collecting has been a hobby for over 100 years. Going for topical（关于某个主题的）stamps is a good way to appreciate its pleasure.
