Numismatic Guaranty Company (NGC) is an international

Blackstone, a multibillion-dollar New York City hedge fund.[1]

History

NGC was founded in 1987 in

Parsippany, N.J. by John Albanese, who also founded Professional Coin Grading Service. A majority stake was later purchased by coin dealer Mark Salzberg. Along with CEO Steven Eichenbaum, Salzberg owns the CDN Greysheet, a price guide for coins similar to the Kelley Blue Book.[2]
NGC commenced operations at its new location in
Certified Guaranty Company (CGC)
, Certified Sports Guaranty (CSG), and Classic Collectible Services (CCS). In 2008, ancient coin certification began (NGC Ancients). NGC has other locations in Hong Kong, China; Shanghai, China; Munich, Germany; and London, United Kingdom.[3] In 2021 Certified Collectibles Group was acquired by Blackstone.[4] Also in 2021, owner Mark Salzberg's son Andrew (formerly of ModernCoinMart) was appointed Executive Vice President of NGC.[5]

Claimed endorsements

In 1995, NGC was named the official grading service of the ANA, though this is purely for marketing purposes as the ANA does not encapsulate coins in its collection.[6] In 2004, NGC became the approved grading service of the PNG.

NGC certifies most US, world, and ancient coins, tokens, and medals. The certification process consists of authentication, grading, attribution, and encapsulation in plastic holders or

Third Party Grader
(TPG). In their investigation, Coin World sent the same coins to each grading service over the course of a year, each coin being graded by all Third Party Graders it was sent to. They found that "In no case did the grading services agree on the grade of any given coin, and in some cases the difference in grading was as much as seven points off".

The NGC grading scale is based on the 70-point

mint errors
, specifying the particular error in addition to a numerical grade.

NGC has used EdgeView

Presidential Dollar series and for all other coins since 2008. Since 2009, a scratch-resistant holder coating, similar to that used on eyeglass lenses, has been employed. NGC offers Oversize holders for coins larger than 45 mm and up to 120 mm, and Mega holders for coins larger than 120 mm and up to 180 mm.[10] NGC's label lists a coin's denomination, variety, grade, pedigree, serial number, and other info.[11][12]

Online research tools

NGC Cert Lookup verifies all NGC-certified coins and helps combat holder counterfeiting. Using the label serial number, NGC will reveal a coin's date, denomination, grade, photo (if any), and pricing and Census info. NGC Coin Explorer lists key info about many coin issues, such as mintages and values.[13] The NGC Census reports how many examples of each issue NGC has certified by grade, which helps determine relative rarity. Census figures are often falsely inflated due to resubmissions of the same coins. NGC Coin Price Guide lists pricing data for most US coin (and some modern Chinese) issues. NGC Auction Central reports auction prices realized.[14]
