Platinum Sponsor: Numismatic Guaranty Company (NGC)

NGC logoNumismatic Guaranty Company (NGC) is one of the most important numismatic companies in the world. As a leading coin authentication and grading service, NGC grades and encapsulates more than a million coins each year! And every NGC holder bears the PNG logo on its hologram label, clearly demonstrating that they value our partnership as much as we do.

There is a simple reason why NGC grades so many coins: prices realized. A coin graded by NGC will consistently fetch more money from a buyer than an ungraded coin. It’s as simple as that.

Why NGC Grading?

NGC hologramThe advent of third-party grading in the 1980s revolutionized the coin collecting hobby by providing impartial opinions of a coin’s grade and authenticity. Prior to third-party grading and authentication, it was easy for sellers to overstate a coin’s grade and many counterfeit and altered coins were unwittingly sold as genuine.

In 1987, NGC was established to provide a fully independent opinion of a coin’s authenticity and grade. From the beginning NGC focused on only one objective, a standard of consistent, impartial and accurate grading. NGC graders are prohibited from buying and selling coins commercially, which prevents conflicts of interest. The expert and impartial grades assigned by NGC and backed by the NGC Guarantee give buyers and sellers greater confidence, increase liquidity and result in higher prices realized.

Collectors and dealers around the world have embraced NGC certification and as a result, NGC has become the world’s largest third-party coin grading service with more than 61 million coins certified.

In addition to its grading and authentication services, NGC’s website is the numismatist’s number one resource for research tools including the NGC U.S., World and Chinese Modern Coin price guides, NGC Auction Central and NGC Coin Explorer.

NGC has also launched a comprehensive Counterfeit Coins Detection portal. It features the 50 US coins, 25 Chinese coins and 25 world collector coins most commonly targeted by counterfeiters, according to submissions to NGC. Each of these coins has on its own page comprehensive information including high-resolution images, the type of counterfeits typically seen, detection tips and other helpful details.

The NGC Counterfeit Detection portal is designed to help collectors, dealers and others identify counterfeit and altered coins before they purchase them, stopping these spurious coins from entering the numismatic marketplace.

Collectors and dealers around the world have embraced NGC certification and as a result, NGC has become the world’s largest third-party coin grading service with more than 61 million coins certified.
