What Is NGC Grading?

What Is NGC Grading? NGC is one of the two most trusted names in coin authentication and grading. Understanding what NGC is and what its certification actually means is essential knowledge for making informed purchases. What Does NGC Stand For? NGC stands for Numismatic Guaranty Company. Founded in 1987 in Parsippany, New Jersey, NGC is one of the two leading independent third-party coin grading services in the world, alongside PCGS. What Does NGC Do? NGC performs two fundamental services: authentication and grading. Authentication determines whether a coin is genuine. Grading assigns the coin a numeric grade on the 70-point Sheldon scale. Once NGC authenticates and grades a coin, it is sealed in a tamper-evident plastic holder called a slab. NGC and World Coins One area where NGC has particular strength is world and ancient coins. NGC certifies coins from virtually every country and era, applying consistent grading standards to pieces that many U.S.-focused collectors find harder to evaluate. Commonwealth Coins and Collectibles carries NGC-certified coins at www.ccandc.gold. Shipping nationally and internationally from Alexandria, Virginia.
