Under this new eBay policy, coins being listed by a seller that has not been certified and encapsulated by either Professional Coin Grading Service, ANACS, Independent Coin Grading, Numismatic Guaranty Corporation of America, or NGC affiliate Numismatic Conservation Services are considered “raw” coins and subject to a different set of listing criteria than may be used for coins graded and encapsulated by one of these sanctioned coin grading services.
