Details Grading Overview
Of the many thousands of collectible coins in the hands of dealers and numismatists, some bear surface conditions that preclude NGC’s graders from arriving at a recognized numeric grade. For these coins, we use NGC Details Grading.
Each coin receives a grade that relates the amount of wear present due to metal loss during circulation. To view our Details Grading scale, click here.
Following the Details Grade will be a description of the noteworthy surface condition. In rare instances, there may be more than one surface condition listed. Many problematic surface conditions occur naturally, but more often than not, they are the result of mishandling over the years, whether deliberate or inadvertent. Once identified, the surface conditions are noted with descriptive terms. For a complete glossary of Details Grading terms, click here.
In the past, coins with problematic surface conditions were given Details Grades and were encapsulated by NGC’s affiliated conservation company, Numismatic Conservation Services (NCS). NCS no longer performs grading and encapsulation, and all coins not eligible for numeric grading will now be graded and encapsulated by NGC under its Details Grading service. Coins already encapsulated by NCS may be resubmitted to NGC for Details Grading at just the nominal ReHolder fee. Submitters will not have to pay a ReGrade fee for NCS-holdered coins to be encapsulated under NGC’s Details Grading service.
