To be sure the silver eagle dollar coin you are about to purchase is genuine
, you may want to ask the vendor a certification and authentication papers of the said coin from ANACS. American Numismatic Association Certification Service is the world's leader in old coin grading, authentication and certification. It does scientific way of grading using state of the art tools, procedure and standards. ANACS was established by the American Numismatic Association in 1972. Its original function was to eradicate the proliferation of counterfeit and altered coins through education. It was then estimated that one out of ten valuable coins traded could either be fake or altered. This finding had raised the ANACS concern to people who had no idea about this and had compounded the creation of counterfeit detection service. Before this service had gone into full operation the ANACS graders began to share their knowledge in counterfeit detection by writing articles in ANA's monthly journal, The Numismatist. Due to growing numbers of people having interest in collecting coins, the ANA published a book containing a collection of its articles relating to coin detection. Soon that time the ANACS built what seemed to be a photographic library of the counterfeit coins it had collected since it started to receive clients for coin grading and certification. ANACS has made significant contribution to the industry of coin collecting. To make sure the money will not be wasted to valueless coins, always ask for ANACS certified coins like 2009 ANACS MS70 Silver Eagle Dollar.
