Unit 6 How long have you been collecting shells? 同步阅读（1） by Lindsey Miller Collecting Coins is My Favorite Hobby Collecting coins is not quite as easy as collecting stamps, but beginners can start by going through the change in their pockets, that is, collect coins which are in circulation（流通）. I have been collecting coins since I was ten. Someone who wants to start a collection can also contact（联系）a club for coin collectors or ask a relative or a friend who collects coins. Experienced collectors usually have more than one coin of a certain kind and will not mind sharing the extra ones. They can also provide helpful advice about where to buy old or rare coins. A collection can be built around any theme, but coin collectors often arrange their collections based on where and when the coin was made. As with coins, you do not need a lot of special tools or equipment（设备）. You do need a safe place allowing you and your friends to enjoy them. You can hold the coins with your bare hands, but you should wear gloves if it is a valuable（有价值的）coin. Never touch the face or back of a coin. The dirt on your fingers will destroy the surface of the coin. Neither should you ever clean an old coin --- if you do, the coin will lose its value. You can clean ordinary coins if you wish: copper（青铜的）coins can be cleaned with vegetable oil and silver（银色）coins with common soap. After cleaning the coins, wipe them with a clean cloth. Never use any strong or dangerous chemicals. (责任编辑：admin) |
