The Chinese Government is allowing their citizens to flood the United States with counterfeit collector coins. The situation has gotten so bad that some of the old circulated silver dollars that you might see in flea markets and antique stores are counterfeits. They have even been able to fool the certification companies a number of times. It is a serious concern for the hobby.
They have also duplicated the American Silver Eagle which is one of the bullion coins that silver investors buy and sell. They even made a bogus Proof ASE in the genuine U.S. Mint packaging.
These “Chinese Dollars” don’t contain any silver. Some of them attach to a magnet; most of them don’t.
Here is a Chinese fake Proof American Silver Eagle in a genuine box with a Certificate of Authenticity.
