Coin counterfeiting
(重定向自Counterfeit coin)
Coin counterfeiting of valuable antique coins is common; modern high-value coins are also counterfeited and circulated.
Counterfeit antique coins are generally made to a very high standard so that they can deceive experts; this is not easy and many coins still stand out.
