Frequently Asked Questions

NGC Grading

Does NGC grade mint errors?

Yes. NGC will grade most circulation issue mint errors as well as most Proof mint errors struck prior to 1985. Mint errors struck after that date are evaluated for NGC grading on a case-by-case basis. NGC does not recognize as mint errors those coins with minor die chips, breaks, rotations, etc., which fall within our interpretation of mint tolerance. The determination of what constitutes a mint error is solely at the discretion of NGC.

Mint error attributions require that the "Mint Error" service be selected on the submission form. There is an additional fee of $15 for mint error attributions.

What coins will not be graded by NGC?

NGC will not grade coins that are counterfeit, are of questionable authenticity or have been altered. In addition, NGC will not grade coins that have active surface contaminants such as PVC residue. These coins will often be eligible for NGC certification after conservation by Numismatic Conservation Services (NCS), an independent affiliate of NGC.

What does it mean if my coin was returned with a label that says "Questionable Authenticity"?

If NGC graders believe that a coin is likely not genuine but its research is inconclusive, the coin will be labeled "Questionable Authenticity" and not encapsulated. The grading fee will be refunded less a $5.00 processing fee.

What does it mean if my ancient coin was returned with a label that says "Authenticity Unverifiable"?

NGC Ancients will only grade coins that it believes to be genuine. If, after evaluation and researched by our staff experts and/or outside consultants, the coin's authenticity cannot be ascertained, the coin will be labeled "Authenticity Unverifiable" and not encapsulated. The full grading fee will apply.

For more information, click here.

Note: NGC no longer uses the term "Authenticity Unverifiable" for US and world coins.

What is "Not Suitable for Certification?"

On occasion, NGC will return a coin as NOT SUITABLE FOR CERTIFICATION. This is used for coins that are severely damaged or otherwise impaired. The surface condition of these coins makes it impossible for NGC to render a conclusive opinion about authenticity, NGC Details grade or both. When a coin is determined to be NOT SUITABLE, NGC will refund the grading fee, less a $5 processing charge.

What are "Early Releases" and "First Releases"?

NGC offers the "Early Releases" and "First Releases" designations for selected coins received by NGC or an NGC-approved depository during the first 30 days of release. The term “EARLY RELEASES” or “FIRST RELEASES” will be noted as part of the coin’s description on the NGC certification label. For a list of eligible coins and cutoff dates, click here

Early Releases and First Releases coins are listed separately in the NGC Census. They are also eligible for inclusion in the popular NGC Registry. In certain markets NGC will offer bilingual Early Releases and First Releases labels. The same definitions, cutoff dates and NGC Registry treatment applies.

What is the difference between the NGC Plus () Designation and the NGC Star () Designation?

NGC assigns the Plus () Designation to coins at the high end of their assigned numeric grade. For example, a coin is graded NGC MS 64 if it approaches the quality of a coin graded NGC MS 65.

NGC assigns its trademarked Star () Designation to coins that have exceptional eye appeal for their assigned numeric grade.

Learn more about NGC Plus () and Star () Designations >

What is an NGC Details grade?

NGC assigns an adjectival NGC Details grade to coins that have surface conditions that preclude numeric grading. These surface conditions include improper cleaning, scratches and damage. Learn more about NGC Details grading >

Why don't NGC Details-graded coins receive a numeric grade?

Numeric grades give a strong indication of a coin's value relative to its value in other grades. Most collectors and dealers would pay more for an MS 64 than an MS 63. This is not necessarily the case for coins that have received NGC Details grades.

The value of NGC Details-graded coins is much more subjective due to the variety and severity of the surface problems that result in NGC Details grades. It depends a lot on one's personal preference. Some collectors may prefer an XF Details Improperly Cleaned coin to an AU Details Scratched coin, while for others it may be the opposite.

If NGC were to assign numeric grades to coins with surface problems, it might imply that higher graded examples would be worth more than lower graded examples. That would not always be the case, however, depending on the type and severity of the problem. An MS 64 Scratched coin would not necessarily be worth more than an MS 63 Improperly Cleaned coin; it could be the opposite.

To avoid this potentially confusing scenario, we describe an NGC Details-graded coin's condition with an adjectival grade range along with a statement of the primary surface problem. We also print "DETAILS GRADE DOES NOT DETERMINE VALUE" on the NGC certification label for added clarification.

What is a "CrossOver" and what grading companies qualify for this service?

NGC offers a CrossOver service that allows submitters to send their PCGS-holdered coins and have them graded by NGC only if the coins will receive an NGC grade that is the same (or higher) as the grade in the PCGS holder. If the coin will not receive the same (or higher) grade at NGC, it will be left in the PCGS holder and returned to the submitter. This helps the submitter avoid the risk of receiving a lower grade than the one assigned by PCGS.

Only PCGS-holdered coins are eligible for NGC's CrossOver service. Coins holdered by other companies must be accompanied by a consent form authorizing NGC to remove the coins from the holders and grade them "raw" (not in the holder).

Learn more about submitting coins holdered by other companies here >

Why was my coin encapsulated in an older NGC label?

In rare instances, certain coin types cannot be encapsulated with the requested NGC label or will be encapsulated with an older NGC label type. While NGC maintains holders that can fit virtually every coin size, unusual coin sizes or more fragile coins may need to be encapsulated with a particular holder and label type. NGC will use its best efforts to accommodate eligible submissions with the requested holder and label type, but it may not be able to fulfill all requests.

If a coin is removed from an NGC holder can I be assured that it will receive the same grade if resubmitted to NGC?

No. Once a coin is removed from an NGC holder the NGC Guarantee no longer applies. This is because NGC cannot account for where that coin has been, what if anything has been done to it, and for the overall subjective nature of coin grading itself.

What is a pedigree?

A pedigree describes the current and/or past ownership of a coin. It notates the collector or collectors who have previously owned a particular coin. For example, a coin from the Eric P. Newman Collection may be pedigreed “Eric P. Newman” or “Newman” on the NGC certification label. NGC will pedigree coins to significant collectors or collections if sufficient documentation is provided.

Pedigrees can also be used to describe hoards. A submitter may request that their own name or the name of a collection be listed as the pedigree on the NGC certification label, subject to NGC's approval.

Does NGC recognize varieties? Is there a fee?

NGC recognizes many major varieties under its VarietyPlus® attribution service. Most variety attributions require that the "VarietyPlus" service be selected on the submission form. There is a $15 fee for most VarietyPlus varieties.

To see a list of eligible varieties and attribution tips, visit VarietyPlus

What does it mean when an NGC-certified Silver Eagle says "Struck at West Point Mint," "Struck at San Francisco Mint" or "Struck at Philadelphia Mint?"

The US Mint currently strikes bullion American Silver Eagles at the West Point, San Francisco and Philadelphia Mints. Although these coins do not have mintmarks, NGC is able to identify the mint facility that struck the coins if the coins are received by NGC in the original, sealed 500-coin green box (commonly called a "monster box").

Bulk submitters of original, sealed monster boxes can request that NGC attribute the mint facility on the NGC certification label. The mint facility will be identified on the NGC certification label by a mintmark in parentheses after the coin's date and the additional text "Struck at (Mint Facility)." The mintmark is in parentheses to indicate that it is not actually present on the coin.

For example, a coin struck at the San Francisco Mint in 2017 will be described as a “2017(S) EAGLE S$1” with the text “Struck at San Francisco Mint” above. These descriptions can appear in combination with NGC Releases Designations, authentic hand-signed labels and other special NGC labels.

NGC's attribution of mint facilities for bullion American Silver Eagles is covered in more detail here.

What do I do if I think my NGC-certified coin is overgraded?

NGC offers a free Appearance Review service in the event that someone believes that an NGC-certified coin is overgraded. Coins that are reviewed and downgraded by NGC are covered by the comprehensive NGC Guarantee of grade and authenticity. To read the full NGC Guarantee, click here.

What do I do if I think my NGC-certified coin is undergraded?

If you believe your NGC-certified coin is undergraded, you may submit it to NGC under the "ReGrade" service tier. An applicable grading tier must also be selected.

Why do I need to list my coin's value on the submission form? How do I know its value?

NGC uses the submitter's declared value to insure the coin while it is in its care. The coin's value also determines the NGC grading tier. Since NGC guarantees the authenticity and grade of coins that it certifies, it charges a higher fee for more valuable coins. For more information, read the Declared Value Policy.

NGC does not value or appraise coins but it does provide several price guides on its website to help collectors find their coin's value.

Can I send multiple submissions to NGC in the same box?

Yes, you may send multiple submissions to NGC in the same box. You may not, however, send submissions to NGC and another independent affiliate (e.g. NCS or PMG) in the same box.

What should I do if I have a Walkthrough or Express submission?

If you have a Walkthrough or Express submission we recommend writing "WK" or "EX," respectively, in bold letters on the outside of the box that you send to NGC. This will help to ensure that these packages are opened first.

Can I drop my coins off at your office?

NGC accepts submissions from collector members through the mail or at shows only. We cannot accept submissions from collectors at our office. NGC Authorized Dealers may drop off their coins at our office if they make an appointment. To schedule an appointment, contact NGC Customer Service at or (+1) 800 NGC COIN (642 2646).

Do you buy, sell or appraise coins?

No. NGC does not buy, sell or appraise coins in order to maintain its independence. NGC is focused on providing expert and impartial assessments of authenticity and grade.

What measures are in place at NGC to ensure the safety of my coins?

NGC headquarters is a secure 60,000 square foot purpose-built facility with two large vaults, a staff of armed guards and more than 150 security cameras. Submissions to NGC are opened under security cameras and each coin is immediately assigned a unique identification number that is used to track it throughout every stage of NGC's grading process. All coins are fully insured while in NGC's possession and are handled only by trained staff.

What is the NGC grading process?

When a submission is received by NGC it is opened by trained staff under security cameras. Each coin is entered into NGC's proprietary system and assigned a unique identification numbered with a barcode that is used to track the coin throughout the NGC grading process. At this stage, the coins are separated from the submission paperwork so that the NGC graders never know the submitter's identify, which ensures impartiality.

Coins are then transferred to the NGC grading room, where multiple professional graders carefully examine each coin. After grading, coins are encapsulated in NGC's EdgeView® holder, the same holder that was extensively tested by the Smithsonian Institution and is currently used to protect more than 300 of that museum's greatest rarities.

After encapsulation, coins are returned to the NGC grading room for a final inspection. Images are then taken of the encapsulated coin for NGC's free online Verify NGC Certification tool, available at

Finally, the coins are matched up to the original submission form and brought to NGC's shipping department. Every coin is individually counted and checked against the submission paperwork to make certain that no mistakes occurred. Coins are then securely packaged in a sturdy cardboard box that contains dividers so that the NGC holders do not come into contact with each other. The NGC-certified coins are now ready to be sent back to the submitter.

Can I check the status of my submission online?

Yes! NGC Collectors Society and NGC Authorized Dealers may login at to track the status of their submission. Submitters may also contact NGC Customer Service at or call 1-800-NGC-COIN (642-2646).

What is NCS conservation?

An independent affiliate of NGC, Numismatic Conservation Services (NCS) was established in 2001 as the world's first professional coin conservation service. NCS conservation removes harmful surface contaminants, stabilizes a coin for long-term preservation and can dramatically improve a coin's eye appeal. After conservation by NCS, coins can be seamlessly transferred to NGC for grading.

NGC Certification Verification

Why do I need to select the grade along with the NGC certification number?

This is done to prevent people from browsing or "crawling" submissions in the NGC Certification Verification database. We understand that this added step can be a little inconvenient, but it provides significantly greater data security.

Why does it say "No match was found"?

There are several possible reasons no match was found:

  • You entered an invalid certification number. Please double-check the certification number and try again.
  • You selected the wrong grade. Please double-check the grade and try again.
  • Your coin has not yet been shipped by NGC. Only coins that have been shipped can be searched in NGC Certification Verification.
If you still cannot find your coin, contact NGC Customer Service.

What does it mean if it says, "Contact NGC Customer Service," "Possible Counterfeit Holder," "Mechanical Error" or "Deleted"?

Contact NGC Customer Service: If you see this alert, contact NGC Customer Service to inquire about this coin. There are a variety of reasons why "Contact NGC Customer Service" may be displayed.

Possible Counterfeit Holder: If you see this alert, it means that NGC has seen a counterfeit or tampered holder that uses this certification number. Contact NGC Customer Service if you see this alert. Also, see the NGC Security Center.

Mechanical Error: If you see this alert, it means that the label has a mechanical (typographical) error. This coin should be returned to NGC so that the label can be corrected. For more information and submission instructions, contact NGC Customer Service.

Deleted: If you see this alert, it generally means that the coin was removed from the NGC Census population report. Coins are occasionally deleted in error, however, so if you see this note but own the coin, please email pictures of the front and back of the holder to
