Mirror-Clone Grading Websites: The Newest Counterfeit Scam Targeting Coin Collectors

When Even the Website Is Fake

Most collectors know to verify a coin's certification number before buying. But what happens when the verification website itself is a counterfeit? That's the reality of mirror-clone grading websites — sophisticated replicas of the PCGS and NGC certification verification pages, designed to make counterfeit coins appear authentic.

How the Scam Works

The operation is layered:

A counterfeit coin is placed in a counterfeit slab. The fake holder includes a fake certification number and a QR code.
The QR code on the slab points to a clone website — not to pcgs.com or ngccoin.com, but to a look-alike domain.
When the buyer scans the QR code or visits the clone site, they see what appears to be a legitimate verification page with all the expected information: coin description, grade, population data, and even images copied from the real grading service's database.
The buyer, believing they've verified the coin, completes the purchase — and ends up with a counterfeit coin in a counterfeit holder, "verified" by a counterfeit website.

Documented Fake Domains

Multiple fraudulent domains have been identified by numismatic researchers and industry watchdogs. Known examples include:

pcgs-cn.com — A Chinese-registered domain mimicking the PCGS verification interface.
pcgsn.com — Registered through Alibaba Cloud Computing Ltd (HiChina). Nearly identical to pcgs.com with one added letter.
pcgs.cn — Uses the Chinese country-code top-level domain.
pcgsverify.cn — Adds "verify" to the domain name for false credibility.

These are just the known examples. New domains are registered regularly, and old ones are sometimes taken down only to be replaced by new variations.

How to Protect Yourself

1. Always type the URL manually.

The only legitimate verification URLs are:

PCGS: pcgs.com/cert
NGC: ngccoin.com/certlookup

Bookmark these pages. Never follow a link from a QR code on a slab you haven't already verified through other means.

2. Check the domain carefully.

Red flags include:

Any domain other than pcgs.com or ngccoin.com
Domains ending in .cn (Chinese country code)
Extra characters: hyphens, added letters, misspellings (pcgsn.com, pcgs-cn.com)
Subdomains designed to mislead (pcgs.verify-coins.com, etc.)

3. Use PCGS NFC authentication.

For PCGS holders produced since October 2020, the NFC tap is the strongest countermeasure available. The chip communicates directly with HID's cloud authentication server using a cryptographic one-time password. This cannot be replicated by a clone website because the authentication happens between the physical chip and the server — not through a browser.

4. Verify cert number results match the physical coin.

Even on the legitimate verification sites, check that the description, images, and grade returned match the actual coin in the holder. Some counterfeiters use real cert numbers from legitimate coins but place a different (counterfeit) coin in the holder.

5. Use the official mobile apps.

The PCGS and NGC mobile apps connect directly to the genuine databases. They're harder for counterfeiters to intercept than browser-based verification.

What PCGS and NGC Say

PCGS has published official warnings about counterfeit holders and clone websites, advising consumers to verify certificates exclusively at pcgs.com/cert. NGC's Security Center warns about social media scams and emphasizes that NGC will never randomly contact people to solicit coin purchases.

The Bigger Picture

Mirror-clone websites represent the most sophisticated evolution of numismatic fraud to date. They attack the one thing collectors have been told to trust: the verification system itself. The defense is straightforward but requires discipline: type the URL yourself, every time, and verify that what you see matches what you're holding.
