Many people want to buy old, old coins (硬币). But, before you part with your good money, watch out! You may be buying a coin that is really a fake(假货).
Experts tell us that the making of fake coins goes back 2, 000 years. In the old days, those who faked coins were punished(惩罚)with death. But now the making and selling of fake coins is a legal business.
Some of the fake coins are made so well that they are listed in coin books. And these coins are sought after by collectors. They will pay a high price for them. It is one thing to buy a fake coin when it is sold as a fake. But it is another thing to buy a fake coin when it sold as the real thing. The best advice is always to buy from a reputable(声誉好的)dealer(商人).
The dealer will take back a coin if it should prove to be a fake one. But this advice is hard to follow if you visit other countries yourself. You might be tempted to buy coins“from the soil”rather than from a dealer. And many of these fake coins do come right from the soil. The fake coins are buried in secret. Then they are dug up in front of witnesses. The dealers themselves can be fooled by this.
Another trick is for someone who sells postcards to have one fake coin. It is a copy of a rare(稀有的)coin and is placed among some real but common coins. The visitor sees the real coins. The visitor thinks then that the rare coin is real too. When this happens, the visitor has been tricked. So, if you decide to buy old coins, be careful !
