CCG to Open London Office at Spink’s in Bloomsbury

Posted on 2/1/2018

The new office will make it easier for many more collectors and dealers to submit to NGC, NCS, PMG, CGC and CCS. The CCG and Spink spaces will be completely independent.

The Certified Collectibles Group (CCG) is excited to announce that it will open an office in London in 2018. The new location will accept submissions to the independent members of CCG, which include Numismatic Guaranty Corporation (NGC), Numismatic Conservation Services (NCS), Paper Money Guaranty (PMG), Certified Guaranty Company (CGC) and Classic Collectible Services (CCS).

CCG’s London office will be in the fashionable Bloomsbury area of London, just steps from the British Museum. It will occupy the third floor of Spink’s headquarters. Established in 1666, Spink is the leading UK-based collectibles auction house with a dominant position in many areas of numismatics and an unparalleled global reach through a network of long-established auction rooms in New York, Hong Kong(China), China, Switzerland and Singapore. The CCG and Spink spaces will be completely independent.

NGC, PMG and CGC are the world’s largest third-party coin, banknote and comic book certification services, respectively. Each company employs a team of specialists who authenticate collectibles, assign a grade on an internationally recognized scale and then encapsulate the collectibles in secure holders designed for long-term preservation. Collectibles certified by NGC, PMG and CGC are backed by the respective company’s guarantee.

These companies focus solely on providing expert and impartial certification services for collectibles. None of the CCG companies buy or sell collectibles, and their employees are prohibited from dealing in collectibles. In addition, their graders never know the identity of a collectible’s submitter, another measure to prevent any conflict of interest.

Certification by NGC, PMG and CGC has added transparency, confidence and liquidity to collectibles markets around the world. This has led to higher prices realized for NGC-certified coins, PMG-certified banknotes and CGC-certified comic books. Together, the companies have certified more than 46 million collectibles.

In addition to certification services, CCG provides professional coin conservation services and professional comic book restoration services through its independent member companies NCS and CCS, respectively.

Submissions to the CCG London office will be handled by NGC International UK Ltd. (NGC UK), a wholly owned subsidiary of NGC. Collectibles submitted to NGC UK will be transported with full insurance coverage (based on the submitter’s declared value) to the CCG companies in the United States for authentication, grading and encapsulation. The collectibles are then transported back to NGC UK to be delivered to the submitter.

"Third-party certification from services such as NGC and PMG has helped to expand the coin and paper money markets around the world, and I experience it first-hand every day in Hong Kong(China) at Spink China," said Olivier D. Stocker, Chairman and CEO of Spink. "Our UK and European clients increasingly demand NGC-certified coins and PMG-certified notes, and we are fortunate to offer them these services within our flagship building. Together with PMG and NGC, Spink is thrilled to offer a new leading ‘one-stop shop’ service to collectors and dealers in London."

"The United Kingdom is not only home to a significant number of coin, banknote and comic book collectors and dealers, but it is also a hub for collectors and dealers who travel from other areas, such as Russia, India and the Middle East," said Steven R. Eichenbaum, CEO of CCG. "Together with our Munich office, this London location will provide an enormous region with better access to our coin, paper money and comic book certification services."

The address of the new office will be:
NGC International UK Ltd.
Third Floor, 69 Southampton Row

Additional details, including submission fees and the date of the office opening, will be announced in the near future. For more information, contact NGC UK at

CCG is headquartered in a 60,000-square-foot facility in Sarasota, Florida, USA. In addition to its London office, it has offices in Munich, Shanghai and Hong Kong, as well as 14 Official Submission Centers in cities around the world.
