What is NGC Certification Verification?

Enter a coin's NGC certification number (circled in the image) and grade to confirm its description and grade in NGC's database and, if available, the images of the coin taken by NGC. This tool can help you to verify that your NGC holder is genuine and has not been tampered with.

  • For coins that have a grade of 1 to 70, enter the certification number, select the numeric grade in the dropdown menu and click "Go."
  • For coins that do not have a numeric grade, enter the certification number, select "Non-Numeric" in the dropdown menu and click "Go."
