What is NGC Certification Verification?

This tool can help you to verify that your NGC holder is genuine and has not been tampered with. It can also be a useful starting point to research your NGC-certified coin.


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, view the images of the coin taken by NGC.

  • 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 with an NGC Details grade, select "NGC Details" in the dropdown menu and click "Go."
  • For coins graded by NGC Ancients, select "NGC Ancients" in the dropdown menu and click "Go."
