What does PCGS and NGC graded mean?
Professional Coin Grading Service (PCGS) and Numismatic Guaranty Corporation (NGC) are the leading independent coin grading services whose standards are accepted throughout the numismatic industry. You should only buy coins that are graded by PCGS or NGC. The advent of these two firms in the 1980s transformed the rare coin market. They offer protection for investors and collectors by guaranteeing the grades of the coins which they certify and also virtually eliminate the possibility of counterfeiting. By maintaining meticulous records on the coins that they certify, PCGS and NGC also help dealers, investors and collectors determine the relative rarity of surviving coins which were originally minted between 1795 and 1933.
