Counterfeit NGC and PCGS slabs are a real risk when buying certified coins. Woof, hello fellow coin enthusiasts!
Our collector friend Janez from Slovenia sent me an important question:
“Cooper, can counterfeiters now also replicate the plastic slabs from NGC and PCGS ?”
The honest answer is: Yes. Counterfeit or manipulated slabs do exist. Fraudsters no longer just try to imitate rare coins. Sometimes they also copy certification labels, use genuine certification numbers, or insert counterfeit coins into fake or manipulated holders.
However, NGC and PCGS offer various security features and digital verification options. Those who know what to look for can identify many suspicious slabs and significantly reduce the risk when buying.
What is a slab?
A slab is a sealed coin holder containing a coin that has been examined and graded by an independent grading company.
The certification label usually contains important information such as:
- Country of issue and year
- Face value and coin type
- State of preservation
- special designations such as Ultra Cameo or Deep Cameo
- individual certification number
- Barcode or other digital security features
NGC and PCGS use tamper-evident holders designed to protect the certified piece and facilitate its international identification. However, a professional-looking slab does not automatically guarantee the coin and holder are genuine.
Can NGC and PCGS slabs actually be faked?
Yes. Both complete replicas and manipulated original holders are fundamentally possible.
Three main variations occur:
- A counterfeit coin is inserted into a fake slab along with a counterfeit label.
- A genuine certification number is copied and used for another coin.
- A real Holder is opened, modified, and then reassembled.
The use of a genuine certification number is particularly dangerous. If the buyer enters this number into the NGC or PCGS database, a matching entry does indeed appear. However, this alone does not prove that the offered coin is identical to the originally certified piece.
Therefore, the certification data, the images of the coin, the holder, and the specific purchase offer must always be checked together.
Is checking the certification number sufficient?
No. Checking the certification number is very important, but it should never be the only test of authenticity.
A copied number can lead to a genuine database entry. Therefore, check whether all displayed data exactly matches the coin in question:
- vintage
- Nominal value
- Coin type
- Embossing quality
- State of preservation
- special designations
- Label variant
- visible features of the coin
- Optionally, front and back images may be included.
If images of the actually certified coin are available during the certification process, you should carefully compare them with the coin being offered. Pay attention to small contact marks, minting marks, spots, toning, or other individual details.
A match in general coin data is not sufficient. The decisive factor is whether the specific specimen plausibly corresponds to the images on file.
Cooper’s security check for NGC and PCGS slabs
1. Officially verify the certification number
Access the certification exam exclusively through the official NGC or PCGS website or app.
Enter the number manually or use the provided scan function. Then check all the displayed information.
Suspects include:
- The certification number does not exist.
- The coin shown does not match the one offered.
- The year of manufacture, face value, or grade of preservation may differ.
- The stored label looks different.
- Available coin images show a different specimen.
- The same certification number appears simultaneously in several offers.
A database match is therefore a necessary verification point, but not the sole proof of authenticity.
2. Use the NFC function on newer PCGS slabs
Newer PCGS holders feature an integrated NFC security chip. An NFC-enabled smartphone can read the chip and initiate the authentication process via the PCGS system.
Hold your smartphone against the designated spot on the slab. The test should redirect you to the official PCGS certification page and authenticate the security chip.
Important: Older, genuine PCGS holders do not have an NFC chip. Therefore, a missing NFC signal is not automatically an indication of a counterfeit. First, it must be determined which holder generation the slab originates from.
Furthermore, do not follow unknown internet addresses that merely appear to be a PCGS page. Always check whether the official PCGS domain is actually open.
3. Check NGC QR code and security hologram
For eligible NGC holders, the QR code on the back can lead to the official NGC certification check. Newer NGC holders may also feature a high-security hologram with a unique QR code and an additional security code.
Here too, it’s important to note that NGC has used different holder and label generations over the years. Not every older genuine slab has the latest security features.
Therefore, check:
- Does the code lead to the official NGC website?
- Do the certification number and coin data match?
- Does the hologram correspond to the relevant Holder generation?
- Do the QR code, label, and hologram appear professionally and precisely processed?
- Are there any indications that the hologram has been replaced or covered up?
Do not attempt to scratch off a hologram or mechanically test the holder. Doing so could damage a real slab.
4. Examine the label, font, and printed image.
Counterfeit labels can sometimes be identified by small irregularities.
Pay particular attention to:
- blurry letters or numbers
- unusual fonts
- uneven spacing
- wrong colors
- skewed or misaligned texts
- Spelling errors
- different logos
- unusual paper
- Missing or incorrectly placed security features
However, NGC and PCGS have changed their label designs several times. Therefore, an older label cannot be compared solely with a current one. The design of the respective holder generation is the determining factor.
For PCGS, the publicly accessible Museum of Holder Generations can be helpful. For NGC, the official information on holders and security features should be consulted.
5. Check holder and seal for tampering.
NGC and PCGS slabs are sealed in such a way that opening them usually leaves visible traces. Nevertheless, you should not rely solely on a quick visual test.
Possible warning signs include:
- Cracks or stress points in the plastic
- unusual scratches along the edges
- visible adhesive residue
- uneven transitions
- damaged sealing points
- a crooked inner ring
- loose parts in the holder
- an implausibly positioned label
- visible traces of a previous attempt to open it
However, the weight or subjective feel of the plastic is not a reliable test of authenticity. Different holder generations and formats can vary in material, construction, and weight.
Why deposited coin images are particularly valuable
The best certification check combines database information with images of the actual certified specimen.
Even pieces from the same year can look almost identical in modern gold coins. Nevertheless, many coins possess individual characteristics, for example:
- small contact traces
- fine scratches
- minimal stains
- Toning
- Special features of the minting
- Different positions of milk spots or discolorations
- characteristic surface features
If such details do not match the images provided, caution is advised. However, it must be taken into account that lighting, camera angle, and image quality can alter the appearance of a coin.
A differing photograph is therefore a warning sign, but not conclusive proof. For high-value pieces, NGC, PCGS, or an authorized dealer should be consulted if there is any doubt.
Caution with old NGC and PCGS holders
Older slabs are not automatically unsafe or counterfeit. Both NGC and PCGS have used numerous holder generations throughout their history.
Earlier designs may differ significantly from today’s slabs:
- other logos
- other holograms
- other fonts
- other label colors
- other positions of the barcode
- seven- or eight-digit certification numbers
- no QR code
- no NFC chip
Older holders can be particularly interesting for collectors. Therefore, it would be wrong to classify a slab as a fake simply because it lacks modern security features.
The crucial factor is whether all features are appropriate for the respective time and Holder generation.
Warning signs even before purchase
It’s not just the slab itself that should be checked. The offer and the seller can also provide important clues.
Be especially careful if:
- the price is significantly below the usual market value
- Only blurry or heavily edited images will be shown.
- the back of the slab is not shown
- the certification number was concealed
- the seller does not wish to provide additional photos
- The same images appear in multiple listings.
- No verifiable seller data is available.
- an unusual or unsecured payment method is required
- artificial time pressure is created
- Origin and ownership history appear contradictory.
An exceptionally low price for a rare, certified coin is seldom a lucky coincidence. It’s usually a reason to take a closer look.
What should you do if you find a suspicious slab?
If you have any doubt about an NGC or PCGS slab, you should not open the coin or perform any mechanical tests.
Instead, proceed as follows:
- Photograph the front, back, edges, label, and security features.
- Check the certification number on the official website.
- Compare the coin with available certification images.
- Check that the holder and label are compatible with the relevant generation.
- Contact NGC, PCGS, or an authorized dealer.
- Cancel the purchase if significant doubts cannot be resolved.
For particularly valuable coins, an additional expert examination is advisable. The costs for this are usually considerably lower than the potential loss due to a counterfeit.
The seller remains an important safety factor.
Digital checks and modern security features are very helpful. However, the coin’s origin is equally important.
A reputable specialist retailer should:
- show complete and original product images
- Provide the certification number transparently.
- correctly describe the degree of preservation
- Document existing boxes and certificates
- provide verifiable company data
- Offer secure payment methods
- Expertly answer questions about the coin
- guaranteeing the authenticity of the offered items

Cooper’s conclusion: A genuine database entry alone is not enough
Yes, counterfeiters can imitate coins, labels, and even complete NGC or PCGS slabs. Furthermore, genuine certification numbers can be fraudulently copied.
Therefore, the most important rule is:
Never compare only the certification number. Always check the coin data, available original images, the holder, the label, the security features, and the seller’s reputation together.
For newer PCGS holders, NFC technology offers particularly strong additional protection. For NGC holders, the official certification check, available coin images, and the security features of the respective holder are helpful. Older slabs, however, must be assessed based on their specific holder generation.
And my best paw-tip: If a rare coin is offered at an amazingly low price and the seller simultaneously shows poor pictures, restraint is usually wiser than bargain fever.
Until the next collector’s question!
