Fake PCGS and NGC slabs: how to spot a counterfeit coin holder

Published Oct 23, 2026

By GoldGuy. Updated Oct 25, 2026.

To spot a fake PCGS or NGC slab, look up the cert number on the grader's own website. Compare its photos, grade and description with the coin in hand. Then tap a PCGS holder's NFC chip or scan an NGC holder's QR code, check the label and plastic, and treat any price below melt value as a warning.

What is a fake slab?

“Slab” is the trade name for a grader's sealed plastic holder. A fake slab comes in three main forms. It can be a counterfeit holder, with a fake or a real coin inside. It can be a real holder that was opened and resealed with another coin. Or it can be a copied label with a real cert number on the wrong coin. Each one borrows the trust of a real label. Both graders exclude such holders from their guarantees: PCGS's guarantee doesn't cover coins in tampered or counterfeit PCGS holders (PCGS Guarantee, checked Oct 23, 2026), and NGC's doesn't apply to counterfeit or tampered NGC holders (NGC Guarantee, checked Oct 23, 2026).

Step 1: Look up the cert number on the grader's own site

Every PCGS and NGC holder carries a unique certification number. Type the address yourself, pcgs.com/cert or ngccoin.com/certlookup, rather than following a link, QR code or web address supplied by the seller.

A match isn't proof. Counterfeiters reuse real cert numbers in fake holders, sometimes on many copies of one coin. That warning comes from the Anti-Counterfeiting Educational Foundation (ACEF), which adds that PCGS and NGC have shut off some numbers seen on known fakes (CoinsWeekly, Apr 13, 2023, checked Oct 23, 2026). PCGS itself warns that fakers may copy real cert numbers from public sources onto fake PCGS labels (PCGS FAQ, checked Oct 23, 2026). So compare the images. NGC says it has photographed nearly every coin it has graded since October 2008, and the photos are free on its site and app (NGC Security Center, checked Oct 23, 2026). PCGS Cert Verification can also show a photo of the coin (PCGS, Aug 23, 2023, checked Oct 23, 2026). Check the date, mint mark, toning, marks and any spots against the photo; any mismatch is a reason to stop.

Step 2: Check the holder's built-in security features

PCGS

• NFC chip. PCGS says that as of October 2020 NFC technology is included in all its coin and banknote holders, identified by a symbol of a shield with three bands on the back of the slab and/or in the bottom-left corner. Hold an NFC-capable phone to the holder; it opens the PCGS Cert Verification app or a web page. The chip generates a one-time password that changes on every tap and is validated by HID's Trusted Tag service (PCGS Security, checked Oct 23, 2026).
• Plastic additive. PCGS holders are made from plastic containing an inert additive detectable only by a hand-held reader that PCGS has provided to select PCGS Authorized Dealers (PCGS, checked Oct 23, 2026).
• Older holders. PCGS tells owners to look for the NFC symbol to see whether a holder has a chip at all, so older holders may not have one. No chip on an older holder isn't proof of a fake; rely on the cert lookup and images.

NGC

• Hologram with QR and security code. NGC introduced a hologram in 2023 with a QR code and an eight-digit numerical security code unique to the coin, fused to the back of the holder. Scanning the QR code takes you to that coin in NGC's verification tool (NGC, Jul 25, 2023, checked Oct 23, 2026). Check that the page that opens is on ngccoin.com.
• Label and seal. NGC says its label carries a UV watermark, holographic foil and microprinting, and its holders are sealed by ultrasonic welding that helps reveal tampering (NGC security features, checked Oct 23, 2026).
• Older holders. NGC introduced the QR hologram in July 2023, starting with select bulk submissions to its Sarasota office; NGC said it would expand it to all submissions at its Sarasota, London, Munich, Shanghai and Hong Kong offices (NGC, checked Oct 23, 2026). Older holders may not have it. For those, use the cert lookup and images.

Step 3: Inspect the label and the plastic

Without opening anything, look for:

• fonts, spacing or logos that don't match the grader's examples of the same holder generation;
• label details that conflict with the cert lookup (date, mint mark, grade, designation);
• prongs, edges or inner frames that look different from genuine examples;
• signs of tampering at the seams, such as glue, gaps or tool marks;
• a coin that looks wrong for the grade on the label.

Compare against the grader's own published holder and label images: NGC's Security Center and security features page, and PCGS's holder security page. Collector forums post side-by-side photos of known fakes, which help as context but aren't official.

Step 4: Check the coin itself

A coin inside a sealed holder can't be weighed directly, so you're limited to what you can see: its design details, edge, color and luster, compared with the grader's photo. Counterfeit coins, as opposed to fake holders, often share repeating defects because every coin from a counterfeit die carries the same flaws; PCGS's “From the Grading Room: Fake or Real?” (Kyle Clifford Knapp, Aug 14, 2023) shows examples. That article is about counterfeit coins, not slabs.

Price red flags: use melt and dealer premiums as a reality check

A graded gold or silver coin offered below its melt value, or far below what the dealers we track charge for the raw coin, is a red flag. ACEF puts it bluntly: buying genuine bullion coins at 30 to 50 percent below spot is “a fool's errand”, because there are no discounts in the silver and gold markets (ACEF, checked Oct 23, 2026).

For other common coins, check Peace dollar silver content value and the rest of our melt pages before you buy.

Where fake slabs show up, and how to buy more safely

ACEF has reported suspected counterfeits in PCGS holders advertised on an online classifieds site, and says it tracks hundreds of websites selling fakes (CoinsWeekly, checked Oct 23, 2026). In general, take the most care where a seller is hard to identify or hold to account.

• NGC says the simplest way to avoid fraud is to buy from an NGC Authorized Dealer or other dealers you trust, and notes that NGC itself does not buy or sell coins (NGC Security Center, checked Oct 23, 2026).
• PCGS runs an Authorized Dealer network with a public dealer directory (checked Oct 23, 2026).
• Pay with a method that offers buyer protection, keep every message, and be wary of urgency or prices well below the market. See ways to avoid overpaying for bullion, and for raw bullion, checking bullion when it arrives.

What to do if you think a slab is fake

1. Don't break the holder. The holder itself is evidence, and a grader can only judge an intact one.
2. Keep everything: the listing, receipt, proof of payment and messages.
3. Contact the grader. NGC asks for high-resolution images, receipts and proof of payment, may examine the holder, and if it's fraudulent returns the coin with a letter and images of the fake holder (NGC Security Center, checked Oct 23, 2026). For PCGS, use the contact details on its guarantee page, which also explains what the PCGS Guarantee covers.
4. Contact the seller and ask for a refund, then report it to the marketplace or your payment provider.

Note that neither guarantee covers a coin in a counterfeit or tampered holder (see above). If you want an expert opinion on the coin itself, you can submit it; see submitting a coin for authentication.

Quick checklist

1. Type the grader's site address yourself and look up the cert number: pcgs.com/cert or ngccoin.com/certlookup.
2. Compare the grader's photo, date, mint mark, grade and description with the coin and label in hand.
3. PCGS: tap the NFC chip if the holder has the NFC symbol. NGC: scan the QR code on the hologram and confirm the page opens on ngccoin.com.
4. Check the label fonts, logo and layout and the holder edges and seams against the grader's own images of that holder generation.
5. Look at the coin: does it match the grade and the grader's photo?
6. Check today's melt value and dealer premiums. A price below melt is a red flag.
7. Buy from a seller you can hold to account, and pay with buyer protection.

FAQ

How can you tell if a PCGS slab is fake?

Look up the cert number on pcgs.com and compare the photos and details with the coin, tap the holder's NFC chip with the PCGS Cert Verification app if it has one, and check the label and plastic against genuine examples of the same holder generation.

How can you tell if an NGC slab is fake?

Enter the cert number at ngccoin.com/certlookup and compare NGC's images and details with the coin. Holders made since NGC introduced its security hologram in July 2023 also carry a QR code and an eight-digit security code you can check.

Can graded coins be fake?

Yes. Counterfeiters make fake holders and copy real certification numbers onto them, so a cert lookup that matches is not proof. Compare the grader's photos with the coin and check the holder's security features.

Does every PCGS slab have an NFC chip?

No. PCGS says NFC technology has been included in all its holders as of October 2020, so older holders may not have one. A missing chip on an older-generation holder is not proof of a fake.

What should I do if my slab is fake?

Do not open the holder. Keep the listing, receipt and messages, contact the grading company and the seller, and report it to the marketplace or your payment provider.

Are there fake PCGS and NGC coins?

Yes. Fake holders exist for both graders, and the Anti-Counterfeiting Educational Foundation says it tracks hundreds of websites selling fakes. One warning sign is price: a gold or silver coin offered below the value of its metal.
