The grade is part of the lookup

NGC's tool compares a certification number and grade with its database and can display NGC's images when available. Enter the number from the label; the form says hyphens are optional. Select the numeric grade for a 1–70 graded coin, or the relevant NGC Details, NGC Ancients or Other option.

NGC says the additional grade selection helps prevent automated browsing of its records. A wrong grade can therefore explain a failed search even when the certification number has been copied correctly.

Use the photographs as evidence

Compare the returned description and grade with the coin and label. If images are present, examine the coin, label and holder together rather than checking only that the number exists. NGC's Security Center demonstrates why those comparisons matter.

Missing photographs do not automatically signal a problem. NGC says it has imaged virtually all non-bulk submissions since October 2008; older pieces and some bulk submissions may lack images. An absent image leaves less evidence to compare, so ask for help when other details are uncertain.

When there is no match or an alert

  • No match: recheck both the number and the selected grade. NGC also says records are searchable only after coins have shipped.
  • Possible Counterfeit Holder: NGC has encountered a counterfeit or tampered holder using that number. Contact NGC rather than treating a resolved number as an all-clear.
  • Mechanical Error: the label may have a typographical error. NGC directs users to customer service for correction instructions.
  • Deleted or Contact NGC Customer Service: ask NGC to explain the particular record. These messages should not be reduced to a single assumption about the coin.

Keep record verification and authentication separate

A genuine database record can be misused on a counterfeit holder. The lookup is one part of due diligence, not conclusive physical authentication. It does not prove ownership, a seller's right to sell or a full chain of provenance, and it does not appraise your coin.

Before a significant purchase, resolve discrepancies and understand the seller's return terms. Keep your invoice and photographs with the lookup record. For suspect holders, follow NGC's official advice; a professional may need to examine the actual item.
