Global Standards

NGC Global Leadership

NGC certification combines rigorous grading standards with comprehensive services that span ancient coins, world coins, tokens, and paper money, making it the most versatile certification service in numismatics.

In my experience with international numismatics, NGC has consistently demonstrated excellence across the broadest range of collecting categories. While PCGS may dominate U.S. coin collecting, NGC leads in world coins, ancients, and specialized numismatic categories. NGC certification is particularly valuable for collectors focused on international material, as their expertise spans every major world coinage system. The NGC holder design offers excellent coin visibility, and their comprehensive online services provide detailed information about each certified coin. For collectors building diverse portfolios or specializing in non-U.S. material, NGC certification provides unmatched expertise and market acceptance. Use to research NGC population data and current market values for your specific collecting interests.
