NCS to Offer More Certification Services

Starting September 1st, NCS will offer "Authentication and Encapsulation" and "Authentication and Detail Grading" for problem coins under its conservation service level or directly through a new NCS Certification service level.

In addition to the immediate removal and neutralization of surface contaminants and corrosion, NCS's efforts also include preventative conservation and long-term storage solutions. As part of this mission, NCS will expand its current services to include "Authentication and Encapsulation" and "Authentication and Detail Grade".

Under its current conservation services, NCS accepts all raw and certified coins, tokens and medals. Submissions of certified coins are evaluated to determine what, if any, conservation procedure will be of benefit to the coin. While certified coins that are submitted to NCS are re-graded and encapsulated after conservation, not all raw coins that may benefit from conservation are suitable from encapsulation by the NCS-approved grading service and are returned raw and unprotected as a result.

Effective September 1st, all genuine coins, tokens and medals submitted to NCS will be certified by either the NCS-approved grading service (NGC) or by NCS depending on the condition of the coin's original surface if the submitter selects the "submit coins for grading" option.

By adding this service, NCS can ensure all genuine coins submitted are returned to the submitter in either an NGC or NCS holder, benefiting the submitter and the stability of the coin.

"As our service has grown, we have had many coins submitted that have detrimental surface conditions that can be addressed by conservation, but will still not be suitable for encapsulation by NGC due to damage from a previous improper cleaning or other irreversible surface conditions," says Dave Camire, NCS Director of Operations. "By offering encapsulation after conservation, we can provide a more stable and protective storage unit and enhance the coin's longer-term stability."

The "submit all coins for grading" service option is an optional service under NCS's Conservation Services. Coins will only be submitted for grading by NGC or NCS if the submitter requests it. Coins that are not certified and encapsulated after conservation will be returned in an Intercept Shield holder.

In addition to certification after conservation, NCS will also accept direct submissions for "Authentication and Encapsulation" and "Authentication and Details Grading". Coins submitted through the "Authentication and Encapsulation" service will be authenticated, attributed by variety and encapsulated as genuine. No grade will be assigned. NCS will accept uncertified coins, problem and non-problem coins under this service.

Under the "Authentication and Details Grade" service, coins will be authenticated, attributed by variety and assigned a Detail Grade. The Detail Grade is a description of the details of the coin and a description of the detrimental surface condition, such as "AU Details, Scratched". NCS will only use an alpha grade and will not subjectively assign a "Net" grade. NCS will only accept coins commonly known as problem or "no grade" coins. Any coin submitted under this service level that is suitable for grading as a non-problem coin will be submitted to the NCS-approved grading service for certification. In such cases, NCS grading fees will be waived and a $3 per coin transfer fee will be charged by NCS and applicable grading fees will be charged by NGC.

Submission fees will be based on value, and each coin is charged individually. Variety attribution and error coin identification are included at no additional charge. Submission fees start at $6 per coin.

Submissions are handled in the order they are received with an estimated service time of 10 business days depending on submission volume. For faster service, NCS will offer a $50 per coin, 3-day Expedite service and a $100 per coin, same-day Walkthrough service.

NCS will accept US and World coins, tokens and medals as enumerated in their service agreement and on the website. Initially, NCS will not accept Colonial coins (pre-1793, except 1792 half dimes), ancient coins, California fractional gold, and Proof Mint Errors. For a list of World Coins, contact NCS customer service at 866-NCS-COIN. NCS will accept Hard Times Tokens as listed in Rulau, Civil War Tokens as listed in the Fuld references, and So-Called Dollars as listed in the Hibler and Kappen reference.

"We anticipate this being a very popular service. In fact, we suspect many collectors and dealers will submit their coins through either the Conservation or the Authentication services so they will get all of their coins encapsulated, avoiding the problem of No Grades, and have the option of getting surface problems address through conservation treatment," says Brian Silliman, NCS Assistant Director of Operations.

No encapsulation submissions will be accepted until September 1st. Submissions must be received on a new submission form. To request submission forms, contact NCS Customer Service at 866-NCS-COIN or by e-mail at

Silica Gel Safety Concerns

Many dealers keep a small quantity of silica gel packets in their vaults to help control moisture and inhibit corrosion and tarnish. Recently, the Canadian Conservation Institute issued an advisory warning of the dangers of certain types of silica gel packets and advising against their use.

The type of silica gel in question is an indicating silica gel based on cobalt indicators. This type of silica gel has had its hazard classification changed because it is considered a potential carcinogen (by inhalation) due to the cobalt chloride moisture indicator. According to the press release, cobalt is a skin and respiratory system sensitizer, and any one handling it should take necessary precautions including the use of gloves, lab coat, dust mask and safety glasses.

Due to the dangers involved in using this type of silica gel, we recommend replacing it with an indicating silica gel that is not based on cobalt chloride or the use of a non-indicating silica gel.

Indicating silica gels based on cobalt chloride must be disposed of as a hazardous waste.

NCS is Hiring Again

Demand for NCS has been so strong that once again we are in need of additional staff for submission management, conservation and authentication and grading.

We are looking for a "numismatically minded" individual who is seeking to advance in the field of numismatics. Candidates should posses an interest and background in numismatics, have strong organizational and communication skills. Numismatic background should include authentication, grading, variety attribution and a broad knowledge of coins, tokens and medals. Conservation experience is a plus, but as NCS has developed its own techniques, intensive training will be provided.

This is a full-time position and will require relocating to Sarasota, Florida. NCS offers a comprehensive and competitive salary and benefits package. Successful candidate will need to pass background security checks.

If you think you are the right person for the challenge, send a letter of interest and resume to Brian Silliman at NCS, PO Box 4750, Sarasota, FL 34230; by fax to 719-360-2559; or to

Over $35 Million in Value Conserved to Date


In the 18 months since NCS was founded, over $35 million in rare coins, tokens and medals have been conserved.

"We knew NCS would experience tremendous growth because it is the only service of its kind and the service provided is the best available," says David Camire, NCS Director of Operations. "We are just a little surprised by how much it has exceeded our expectations."

Prior to NCS being founded, the only conservation service that specialized in rare coins, tokens and medals from all periods was based at the American Numismatic Association headquarters in Colorado Springs, CO. The ANA closed their conservation laboratory in January of 2002 and chose NCS as their conservation service of choice.


Many museums and private organization employ or contract work out to professional conservators. Most conservators specialize in one type of artifact or cultural property. A specialized organization dedicated to the conservation of numismatic material and accessible to the collecting community at large was long over due.
