Coins We Grade & Policies
NGC grades most US and world coins struck 1600 to date (or 1300 to date for Western Europe) as well as many tokens and medals (see list). NGC Ancients provides comprehensive grading services for coins from Western ancient civilizations, dating from the inception of coinage to circa AD 500, and coins of the Byzantine Empire (AD 491–1453).
NGC also has a specialty service for shipwreck-recovered coins. Learn more about NGC Shipwreck Certification.

Coins That Are Not Encapsulated
There are several reasons why a coin cannot be graded or encapsulated by NGC. One of the most common of these relates to a coin’s authenticity. Another reason is that the coin has active surface residue. Read more >

Declared Value Policy
Submitters to NGC UK are required to list a declared value for each coin in their submission. By submitting a coin and listing a declared value, the submitter agrees that the declared value represents the current fair market value (FMV) of the submitted coin. The declared value must represent the FMV of a genuine coin of that same issue and variety in the same approximate condition.
If you do not know the coin’s current fair market value, you can assign a declared value based on the price you paid for the coin (if purchased recently), a value you found in a price guide (such as the NGC Price Guide), the price a dealer offered to pay you for the coin or other reasonable determining method.
NGC UK does not assign values to coins. If NGC UK determines that a coin is undervalued and does not qualify for the tier or services selected, it may adjust the tier and charge the appropriate difference in conservation, grading and/or services fees based on its determination of the coin’s current Fair Market Value. (Note: NGC will adjust the tier even if the coin is later determined to be not genuine, altered or otherwise ungradable.) NGC UK will not, however, change the declared value originally assigned by the submitter.
The declared value is used to insure a coin while it is at NGC UK’s facility and, for coins that are shipped by NGC UK to NGC in the US for grading, to insure a coin while it is in transit. In addition, in the extremely rare event that a coin is lost or damaged while at NGC UK’s facility, the submitter will be compensated based on the coin’s current Fair Market Value (as defined below) in the condition in which it was received by NGC UK; provided that in no event will the compensation exceed the declared value listed by the submitter on the NGC UK Submission Form. It is therefore very important that the declared value listed by the submitter represent the coin’s current fair market value.
Fair Market Value: For the purposes of this Policy, the “current Fair Market Value” is the value of the coin if it were to be sold, as determined by NGC UK in its sole reasonably exercised discretion. NGC UK will determine the current Fair Market Value of a coin based upon what NGC UK believes, in its sole reasonably exercised opinion, to be reliable current market information. NGC UK may use actual pricing and sales information available to it, including prices in the actual transaction history of the coin in question. However, due to the volatile nature of the coin market and Internet auctions/sales as well as the differences in buying habits of different individuals, such information may not necessarily represent the accurate current Fair Market Value of any particular coin, which again, will be determined by NGC UK in its sole reasonably exercised discretion. NGC UK reserves the right to use the declared value listed by the submitter on the NGC UK Submission Form as the current Fair Market Value, and in no event will NGC UK’s determination of current Fair Market Value exceed the declared value listed by the submitter on the NGC UK Submission Form. NGC UK’s determination of the current Fair Market Value will be absolute and binding on all parties.
Please note that this policy also applies for submissions to Numismatic Conservation Services (NCS), an affiliate of NGC UK, if NCS conservation services are selected on the NGC UK Submission Form.
Coins with Additive Applications (Jewels, Enamel, and Similar) Policy
NGC UK will accept submissions of coins with additive applications (such as embedded jewels or enamel) only if they are accompanied by NGC UK’s Release for Coins with Additive Applications Form.
While NGC UK and NGC will use its best efforts to protect coins and any additive applications, it is possible that the additive applications may become dislodged or the additive applications or the coin may be become damaged during or after NGC’s normal grading process. As a result, NGC UK and NGC will not be liable for any damages associated with additive applications. The grade of these coins is also not covered by the NGC Guarantee.
CrossOvers / Non-NGC Holders
NGC UK will accept submissions of PCGS-holdered coins for CrossOver service. This service enables 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 the PCGS holder.
NGC UK will not accept CrossOver submissions that request a minimum grade that is higher than the grade listed on the PCGS holder. The “CrossOver Minimum Grade” section of the NGC UK submission form may only be used if the minimum desired grade is the same or lower than the grade on the PCGS holder.
Due to the special verification required, NGC UK does not recognize designations or pedigrees assigned by other grading services if NGC UK requires that the coins be submitted in the sealed mint shipping box. For example, NGC UK requires 25th Anniversary Set American Silver Eagles be received by NGC UK in the sealed US Mint shipping box. Therefore, a PCGS-holdered American Silver Eagle with the 25th Anniversary Set pedigree cannot receive the 25th Anniversary Set pedigree at NGC UK if submitted for CrossOver because NGC UK did not have the opportunity to open the sealed US Mint shipping box to confirm the coin's pedigree. While these coins can still be submitted for NGC UK for CrossOver, they will not receive the set designation or pedigree assigned by PCGS if NGC UK requires that the coins be submitted in the sealed mint shipping box.
For complete CrossOver instructions, click here.
In addition, NGC UK will not accept CrossOver submissions of coins holdered by companies other than PCGS. These coins may still be submitted to NGC UK only if they are accompanied by NGC UK’s Consent to Remove Coin(s) from Holder(s) Form. The coins will be treated by NGC UK as raw (ungraded) submissions.
NCS: No Grade Protection or Guarantee
NGC UK does not provide grade protection or any type of grade guarantee for coins submitted for NCS conservation. Coins are guaranteed by NGC only after they are graded and encapsulated by NGC.
NGC UK evaluates every coin submitted for NCS conservation services to determine whether it believes the coin will benefit from conservation. Special handling, detailed below, applies to submissions of NGC and PCGS-certified coins.
- If NGC UK believes that a coin will benefit from conservation, the coin will be conserved and then transferred to NGC for grading.
- If NGC UK believes that a coin will not benefit from conservation, the coin will not be conserved. In this case, raw (not holdered) coins will be transferred directly to NGC for grading. Only the NGC grading fees will apply.
- If NGC UK believes that an NGC or PCGS-certified coin will not benefit from conservation, the coin will not be conserved and will be left in its original holder and returned to the submitter. The coin will not be transferred to NGC and the NGC grading fees will be refunded less a £5 processing fee.
- However, if NGC UK believes that a PCGS-certified coin will not benefit from conservation but will likely receive the same grade (or a higher grade) with NGC, the coin will not be conserved and will be transferred to NGC for CrossOver. Only the NGC grading fees will apply.
- *Please note that while NGC UK will attempt to accommodate special requests from submitters it can’t be responsible if any special requests are not fulfilled.
Important: Conservation services performed by NGC UK do not necessarily improve a coin’s grade. In rare instances, NGC UK conservation may reveal additional issues that were previously hidden by residue or other surface contaminants. None of the techniques used by NGC UK will cause such issues. It is important to understand that coins conserved by NGC UK may still receive a lower grade or no grade from a coin grading service. By submitting a coin to NGC UK, the submitter waives any right to assert any form of legal claim against NGC UK (and any affiliates, divisions, subsidiaries or other entities related to NGC UK and its and their respective officers, directors, employees, agents and assigns) with respect to a lower grade or no grade subsequently being assigned to such coin by a coin grading company.
NCS Conservation / NGC ReGrade
NCS conservation can help coins with unattractive toning, copper spots and other surface issues. Customers may submit a coin already certified by NGC for a service that includes NCS conservation and an NGC ReGrade (NCS+ReGrade). If NCS declines to conserve a particular coin under this combined service, then NGC will not perform the ReGrade. If the customer wants the NGC ReGrade regardless of the NCS determination, then the customer should write on their submission form: REGRADE REGARDLESS OF NCS DECISION.
Return Packaging Policy
NGC UK will return capsules and other packaging (such as original mint boxes) to submitters who check the “Return Packaging” service on the NGC UK Submission Form. There is an additional £5 fee per submission form for this service, plus any additional shipping costs that may apply.
NGC UK will attempt to return packaging at the same time as graded coins. If the packaging is not returned at this time (e.g. the submitter does not accept the returned packaging), the packaging will be held by NGC UK for an additional 14 calendar days. After this time, unclaimed packaging will be discarded. NGC UK will not be liable for packaging discarded if unclaimed for more than 14 calendar days after the date graded coins are returned to the submitter.
In addition, while NGC UK will use its best efforts to preserve capsules and other packaging in the best possible condition, it is possible that capsules and packaging may be damaged when coins are removed. NGC UK will not be liable for damaged packaging.
Please note that if the “Return Packaging” service is not selected on the NGC UK Submission Form, NGC will discard the packaging once the coins have been removed. NGC UK will not be liable for any discarded packaging.
White Spots on Modern Silver Coins
NGC has a policy for white spots, often called “milk spots,” that can sometimes develop of a variety of modern silver bullion coins from around the world including American Silver Eagles, Chinese Silver Pandas and Canadian Maple Leafs.
