Ancient Coin Authentication, Grading, and Evaluation Services

Guarantee?

None of the authentication services listed below "guarantee" authenticity. What that means is, they aren 't going to give you any money if they are wrong. How could they? You pay them $45 and they are going to guarantee your $5000 coin or even your $500 coin is genuine? These services authenticate coins, providing an unbiased highly expert opinion worthy of considerable respect. They can be wrong but they are more likely to be right than you are (and you means almost everyone). A guarantee can only come from the dealer who sold the coin. Buy from reputable dealers with expertise and a guarantee (Forum Ancient Coins, for example). If you want additional assurance, buy coins certified by the experts below or submit your coins to them for authentication. 

David Sear - Ancient Coin Certification Service (ACCS)

http://www.davidrsear.com/certification.html   

Authenticates and attributes but does not grade or slab. Coins are accompanied by black-and-white photo and certificate. Service of David Sear, author of the Greek Coins and Their Values, Roman Coins and Their Values, and other standard ancient numismatic attribution works.

Charges $45 for basic service or $55 for detailed service. Detailed service includes extra information about the coin 's historical significance.

Turn around up to 8 weeks. With express service, which costs extra $30 per coin (five coin maximum), turnaround time is five working days.

Numismatic Guarantee Corporation (NGC)

https://www.ngccoin.com/submit/services-fees/ngc-ancients/

NGC employs more than 30 full-time coin graders as well as outside consultants.  To ensure impartiality, NGC and its full-time graders do not buy and sell coins commercially, and strict procedures are in place to prevent consultants from influencing the grades assigned to their own submissions.

Coins can be submitted in a number of tiers depending on the value of the coin.  See the above link for tier and fee schedule.

The British Museum, Department of Coins and Medals

https://www.britishmuseum.org/our-work/departments/coins-and-medals#object-identification

The British Museum provides an object identification service, through which we share our professional knowledge and expertise with both professional colleagues and the general public. The Museum does not give valuations, nor do we create documents to supply authentication or provenance investigation services to the general public. Moreover, the Museum: 

Does not give written certificates of provenance, authenticity or valuation (appraisals) to private collectors, buyers or sellers;

Does not give any kind of assurance to private collectors, buyers or sellers in relation to objects offered for sale on the art and antiquities market.

Objects may be brought for identification on Wednesday afternoons by appointment only. Email the relevant collections department with a description of the object and a clear photograph, and a member of staff will contact you via e-mail to book an appointment date when the relevant curator for the object you wish to have examined is available.

CLOSED - American Numismatic Association Authentication Bureau (ANAAB)

http://www.money.org

The American Numismatic Association Authentication Bureau (ANAAB) is no longer accepting submissions for authentication.  The Associations Board of Governors voted at a meeting in New York City to discontinue ANAAB after reviewing a report that suggested the cost of employing a full-time authenticator outweighed the benefits to the membership.  All recent submissions have been returned.






All coins are guaranteed for eternity
