About This Guide
If you are trying to verify an Icons.com Certificate of Authenticity, complete an Icons certificate check, or determine whether an Icons hologram or signed football shirt is genuine, this guide explains what to look for.
Counterfeit signed memorabilia is regularly offered through eBay, Facebook Marketplace and other secondary marketplaces. Fraudsters do not only forge signatures, they also reproduce Certificates of Authenticity, copy serial numbers, imitate holograms and pair them with counterfeit football shirts to create convincing-looking items.
This guide is not intended to question the authenticity or reputation of Icons.com. Before founding X Memorabilia, I spent almost ten years at Icons.com, ultimately as Head of Ecommerce, working closely with the company’s Certificate of Authenticity systems. Icons.com is a genuine and well-established memorabilia company, which is precisely why counterfeiters target its certificates, holograms and branding. This guide is intended to help collectors identify those counterfeit items, not criticise the company behind the genuine ones.
The golden rule of authenticationA Certificate of Authenticity should support authenticity, not create it.
A convincing certificate does not automatically make the autograph genuine. Likewise, a genuine-looking hologram or serial number means very little if the signature, football shirt or provenance does not stand up to scrutiny. The autograph, item, certificate, hologram and supporting evidence should all be consistent and tell the same story.
During my time at Icons.com, I handled thousands of genuine signed items and worked closely with certificate production, including developing automation used as part of the process. That experience gave me a detailed understanding of how genuine Icons.com authentication materials should look, how they have changed over time and the details counterfeiters often get wrong.
This guide focuses primarily on the legacy Icons.com certificates and holograms most commonly found on the resale market. Icons.com began introducing a redesigned hologram around April 2026, with both styles remaining in circulation during the transition. However, the vast majority of counterfeit Icons-branded memorabilia seen to date has attempted to imitate the older certificate and hologram design. This guide explains how to assess the signed item, autograph, certificate, hologram, serial number and provenance together, while highlighting the warning signs commonly found on fraudulent examples.

TL;DR
Do not rely on an Icons.com Certificate of Authenticity alone. Counterfeiters can copy certificates, holograms, packaging and signing photographs.
Check that the underlying shirt or memorabilia is genuine, the certificate details match the item, and the hologram is consistent with confirmed genuine examples. Use the comparison images in this guide to identify known signs of fake certificates, holograms and shirts.
Ask for supporting provenance such as the original receipt or order confirmation. If the shirt, certificate or hologram can be confirmed as counterfeit, the entire signed item should be treated as fake.

What Is an Icons.com Certificate of Authenticity?
An Icons.com Certificate of Authenticity, commonly referred to as an Icons COA, is supplied with memorabilia authenticated and sold by Icons.com. Its purpose is to record information about the signed product and connect it to the company’s authentication process.
The exact design has changed over time, but a typical legacy Icons.com certificate contains several distinct elements.
Signing photograph
On the left-hand side, the certificate will often show a photograph taken during the relevant signing session, where one is available.
This image is generally not unique to the individual item supplied with the certificate. It is usually a sample photograph from the session, included to provide evidence that the signing took place and that an Icons.com representative was present.
Collectors should not attempt to match the precise autograph shown in this photograph to the signature on their own item. In most cases, the item pictured being signed will not be the exact item supplied with that particular certificate.
Example product image
On the right-hand side, the certificate will usually feature an image representing the product.
Again, this is normally an example product photograph, rather than a photograph of the exact physical item owned by the collector. Small differences in the shirt, photograph, ball, boot or signature placement do not automatically indicate a problem.
Product name
The main product title identifies what the certificate is intended to accompany. This may include details such as:
- the player’s name
- the team or country
- the season
- the product style
Item code
The item code is Icons.com’s internal product reference or SKU. It identifies the product line rather than necessarily identifying one unique physical item.
Several examples of the same product may therefore share the same item code.
Signed by
This field states whose autograph should appear on the item. For multi-signed products, more than one name may be listed.
Item type
The certificate normally identifies the general category of memorabilia, such as:
- signed shirts
- signed photos
- signed footballs
- signed boots
The description should be consistent with the accompanying item.
Date signed
Where recorded, the certificate may include the date on which the signing session took place.
A signing date may be absent from some older certificates. It may also be unavailable where the item was supplied by an approved third-party supplier and the original signing information was not provided or recorded in the product data.
The absence of a date is therefore not, by itself, evidence that a certificate is counterfeit.
Location signed
Where recorded, the certificate may include the location of the signing session. This is usually the city, venue or general location where the memorabilia was signed.
A signing location may be absent from some older certificates. It may also be unavailable where the item was supplied by an approved third-party supplier and the original signing location was not provided or recorded in the product data.
The absence of a location is therefore not, by itself, evidence that a certificate is counterfeit.
As with the date, this information may not appear on every generation of Icons.com certificate.
Hologram
The certificate carries a numbered Icons.com hologram. A second hologram bearing the same serial number should be attached to the signed item.
The matching pair is intended to link the physical item to its accompanying certificate. There is not a separate certificate reference number beyond the serial number shown on the holograms.
The numbers should match exactly. However, a matching serial number should not be treated as proof of authenticity on its own, as holograms and serial numbers can be copied or reused.
What Does an Icons.com COA Actually Authenticate?
An Icons.com Certificate of Authenticity is best understood as a record of the product supplied, rather than independent proof that the autograph is genuine.
In many respects, it acts more like a receipt or proof of purchase, recording details such as the item, signer, product code, signing date and location where available.
Its main physical security feature was the pair of matching numbered holograms, with one attached to the certificate and the other to the signed item. However, legacy Icons.com holograms and their serial numbers have now been widely copied by counterfeiters.
A matching certificate and hologram can therefore support authenticity, but they should never be relied upon in isolation.

Don't Rely Solely on the Certificate
One of the biggest mistakes collectors make is treating the Certificate of Authenticity as the only thing that matters.
A genuine-looking certificate, matching holograms and serial numbers do not automatically make the accompanying memorabilia genuine. Legacy Icons.com certificates and holograms have been widely copied, meaning counterfeiters can often produce convincing authentication materials.
Instead, the certificate should be viewed as just one piece of the puzzle.
In the following sections, we'll look at how to assess the signed item itself, examine the autograph, verify the memorabilia, review the holograms and, where possible, obtain supporting provenance such as proof of purchase.
Ask for Supporting Evidence
Ask the seller for any supporting provenance, such as the original receipt, order confirmation, invoice or dispatch email.
You should also ask when and how the item was purchased. A clear account of where it came from and how it has changed hands can add useful context.
Items described as second-hand or third-hand are naturally harder to verify because the original purchase trail may have been lost. However, this explanation is also sometimes used to obscure weak or non-existent provenance, so it should be treated with caution rather than accepted without question.
Supporting evidence does not prove authenticity on its own, but it can help establish whether the story behind the item is credible.
Examine the Item
When assessing whether memorabilia is a genuine Icons.com item, the item itself can be just as important as the certificate and hologram.
Icons.com uses authentic products and officially licensed replicas from recognised manufacturers and approved suppliers. It does not use unofficial counterfeit shirts and then authenticate them as genuine memorabilia.
That makes the underlying item a useful part of the check. If an alleged Icons.com signed shirt is clearly counterfeit, it is a strong sign that the certificate and hologram may also have been copied or misused.
Is the Item Itself Genuine?
Start by checking whether the memorabilia matches the product described on the certificate.
For shirts, confirm the team, season, manufacturer, colourway, sponsor, badges, nameset and numbering. For other items, check that the product type, design and period make sense.
A genuine-looking certificate cannot compensate for an item that is obviously wrong.
Checking Signed Football Shirts
One of Icons.com’s biggest strengths is its long-standing relationship with Lionel Messi, and signed Messi shirts are among the company’s most recognisable and sought-after products. Throughout my time at Icons.com, signed shirts were produced using genuine products, including authentic vintage originals and officially licensed replica shirts from recognised manufacturers and approved suppliers.
The same standard applies at X Memorabilia. We only use authentic vintage original shirts or officially licensed replicas. We do not use unofficial or counterfeit shirts.
This makes the shirt itself one of the most important checks when assessing whether an alleged Icons.com item is genuine.
Fraudsters often take the opposite approach. They buy inexpensive counterfeit football shirts, add a forged autograph, then pair them with copied Icons.com certificates, imitation holograms and even replica Icons.com packaging or gift boxes to make the complete item appear more convincing.
Branded packaging is not proof of authenticity. Gift boxes, presentation cases and inserts can be copied, reused or obtained separately, so they should be treated as presentation rather than authentication evidence.
For modern shirts, one of the quickest checks is the manufacturer’s product code.
On many adidas shirts, the product code can be found on a label inside the collar or elsewhere inside the garment. Search the code online together with the word “adidas” and check that the results match the exact club or country shirt, season and colourway you are examining.
A well-known example is the adidas code HA8870. This is a notorious floating product code that has been printed across many unrelated counterfeit club and international shirts. A genuine adidas product code should correspond to a specific shirt design and colourway, not multiple completely different kits.
Nike shirts can be checked using the product or style code, usually found on an internal label near the wash tags. Search the code online and confirm that it matches the exact shirt design, season and colourway.
Some Nike shirts also feature a Nike Authentic serial number on a label at the front, near the bottom-left of the shirt. These numbers should be unique. Search the serial number online and check whether it appears on another shirt or a completely different shirt style. If the same number is being used across multiple shirts, this is a strong indication that the shirt is counterfeit.
The same principle applies to many other manufacturers that use product codes, style numbers or serial numbers to identify genuine shirts.
Product codes are not available on every shirt, particularly older vintage examples, so the shirt should still be assessed as a whole. Check:
- manufacturer labels and wash tags
- club or national badges
- sponsor printing
- nameset and numbering
- stitching and construction
- material quality
- whether the shirt matches the season and product described on the Certificate of Authenticity
If you can confidently establish that the shirt itself is counterfeit, then the autograph, Certificate of Authenticity and holograms should also be treated as counterfeit. Icons.com only uses genuine shirts, so a fake shirt is one of the clearest signs that the entire package is fraudulent.
Examine the Autograph
Authenticating an autograph from the signature alone is extremely difficult. Experienced fraudsters can become very good at imitating a player’s general style, shape and flow, which means a convincing-looking signature is not proof that it is genuine.
Signatures can also vary considerably. We have seen players sign in two noticeably different ways during the same signing session. Factors such as the item being signed, the available space, signing speed, pen type and fatigue can all affect how an autograph looks. In many cases, even the player themselves would not be able to confirm with complete certainty whether an isolated signature was genuine.
Signature comparison may identify obvious concerns, such as a slowly drawn autograph, unusual letter formation or a signature that differs significantly from known examples. However, it should never be treated as conclusive evidence on its own.
This is why a copied Icons certificate can actually make a fake item easier to identify. Genuine Icons certificates, holograms and product details follow established formats. Counterfeit versions often contain specific errors, inconsistencies or design differences that can be demonstrated and proven.
Unlike an opinion based solely on the appearance of a signature, these certificate errors can provide clear evidence that the COA did not originate from Icons. Once the certificate or matching hologram has been proven fake, the item should also be treated as fake, regardless of how convincing the autograph may appear.
Examine the Certificate and Hologram
The certificate and hologram are often the most useful parts of the authentication process because they contain details that can be checked objectively. While a skilled forger may convincingly imitate the appearance of a signature, fake Icons certificates and holograms often contain repeatable errors that can be identified and proven.
Here are five of the most common warning signs.
1. The certificate description does not match the item
Check that the product name and description on the certificate accurately match the signed item.
For example, a certificate may describe a shirt as having fan-style numbers, meaning plain numbers without club, country or tournament branding. However, the actual shirt may have Barcelona or Argentina branding within the numbers.
This misalignment suggests that the certificate was not originally produced for that item and may have been copied or altered.
2. Incorrect spacing in the hologram wording
Some counterfeit Icons holograms are very close copies of the genuine design, but small differences remain.
One of the most recognisable errors appears in the wording “Signed By The World’s Best”. On known fake holograms, the “W” and “O” in “World’s” are not aligned correctly, leaving an unnatural extra space between the letters.
This is a subtle but repeatable difference that can help identify a counterfeit hologram.
3. Incorrect hologram font or number positioning
Examine the serial number printed on the hologram.
On genuine examples, the numbering uses a consistent font and is correctly positioned within the hologram design. On known counterfeits, the font may look slightly different and the number is often positioned too far to the right rather than being properly centred.
These differences become much easier to identify when the hologram is compared directly with a confirmed genuine example.
4. Spelling mistakes and incorrect wording
Genuine certificates are professionally produced, so spelling mistakes and obvious wording errors are major warning signs.
Known fake certificates have included wording such as “Registeredd Company No.” instead of “Registered Company No.” Errors may also appear in the product title, item type, player name or other certificate details.
Even a single spelling mistake should prompt further investigation.
5. The signing photograph does not match the stated session
Check that the signing photograph is consistent with the signing date and other information shown on the certificate.
Fraudsters often copy signing photographs from genuine Icons certificates, product pages or social media. This can result in a certificate using an image from a completely different signing session.
The player’s clothing, background, table setup and items visible in the photograph can all help establish whether the image genuinely relates to the claimed signing date.
Genuine Icons Certificate vs Fake Examples
The differences between genuine and counterfeit Icons certificates are often easier to identify when examples are compared directly. The following examples show how the shirt, certificate, hologram and signing information should be assessed together rather than relying on the autograph alone.
Genuine Example
This genuine Icons item has a certificate that accurately matches the signed product. The player name, item description, item type and product image all correspond with the shirt.
The certificate uses the correct layout, wording, fonts and spacing for the period in which it was issued. The hologram number is correctly positioned, the wording around the hologram is properly aligned and the matching serial number appears on the signed item.
The signing photograph is also consistent with the date and session details shown on the certificate. When combined with a genuine shirt and credible provenance, all elements align as expected.
Fake Example
This counterfeit example may initially appear convincing because it copies the overall appearance of an Icons certificate and includes matching numbered holograms.
However, closer inspection reveals several identifiable errors. These may include incorrect hologram lettering, an off-centre serial number, the wrong font, spelling mistakes or product information that does not match the shirt.
The shirt itself may also be counterfeit, with an incorrect product code, duplicated Nike Authentic serial number or other manufacturing details that do not correspond with an official product.
Once the certificate or hologram has been conclusively identified as fake, the signed item should also be treated as counterfeit, regardless of how convincing the autograph appears.
Why Traditional Paper Certificates Have Limitations
Traditional paper certificates can provide useful supporting information, but they are relatively easy to copy, edit or reproduce. Product details, signing photographs, logos and hologram numbers can all be replicated and used to support counterfeit memorabilia.
A paper certificate may also use a generic signing photograph or product image rather than showing the exact autograph attached to the item. This means there is often no reliable way for a future buyer to compare the physical signature with the item originally issued with the certificate.
Another weakness is the lack of online verification. Without a searchable digital record, buyers cannot independently confirm whether a serial number was issued, what product it belonged to or whether the same certificate has been reused with several different items.
Matching hologram numbers alone do not solve this problem because counterfeiters can manufacture two fake labels carrying the same number. A genuine paper certificate can also become separated from its original item and later be paired with something else.
For these reasons, a traditional certificate should support authenticity rather than create it. Buyers must still examine the item, autograph, hologram, product details and provenance together.
How CertAuthentic Improves Transparency
CertAuthentic was developed by X Memorabilia after more than 15 years of experience within the signed memorabilia industry. During that time, we repeatedly saw the same weakness with traditional certificates: buyers were often expected to trust a piece of paper, a hologram and the reputation of the seller without being able to verify the exact item for themselves.
X Memorabilia built CertAuthentic to create a clearer connection between the physical item, its certificate and a permanent online record. The aim was not simply to produce another COA, but to address the ways traditional certificates can be copied, reused or separated from the item they originally accompanied.
Each CertAuthentic certificate includes a unique serial number and QR code linking to a digital record for that item. The record can include the product description, supplier details, signing information, images of the complete item and supporting photographs or videos from the signing session where available.
Most importantly, it normally includes a high-resolution photograph of the actual autograph attached to that certificate. This allows the owner or a future buyer to compare the physical signature with the image stored online. If the certificate or hologram is later reused with a different item, the autograph and product details should not match.
The physical certificate is printed on a credit card-style plastic card and includes a numbered security hologram paired with the label attached to the item. However, the card and hologram are not intended to act as proof on their own. They provide access to the more detailed digital record behind them.
Every signed item sold by X Memorabilia comes with a CertAuthentic certificate of authenticity, giving customers access to this additional level of item-specific verification from the point of purchase.
CertAuthentic therefore reduces the need for blind trust. A future buyer can independently check the certificate number, view the recorded item and compare the autograph in front of them with the original image online.
No authentication system can prevent every attempt at fraud. However, item-specific photographs, online verification and permanent digital records make it much harder for counterfeiters to copy a certificate, reuse it with another item or rely on the reputation of a recognised brand to pass off fake memorabilia as genuine.
This is increasingly important because fraudsters are not simply creating generic certificates. They are copying the names, branding and appearance of established memorabilia companies to give counterfeit items false credibility. CertAuthentic provides buyers with evidence they can independently check, rather than asking them to trust the brand name printed on the certificate.
Frequently Asked Questions (FAQs)
Final Buying Advice
When buying Icons.com memorabilia on the secondary market, do not rely on the Certificate of Authenticity alone.
Start with the item itself. Check that the shirt, photograph, football, boots or other memorabilia is genuine and consistent with the product described on the certificate. Then examine the autograph, certificate, holograms and any supporting provenance together.
Ask the seller when and how the item was purchased, and request supporting evidence such as the original receipt, invoice or order confirmation where available. A clear chain of ownership provides far greater confidence than a vague explanation that the item has changed hands several times.
Be particularly cautious if:
- the seller refuses to provide clear photographs
- the item itself appears counterfeit. Icons.com only uses authentic shirts, so check the manufacturer labels and product code
- the certificate details do not match the memorabilia
- the hologram differs from genuine examples
- the autograph differs significantly from known genuine examples
- the seller has very little or no feedback
- the seller says they are not the original owner and cannot answer basic questions or provide provenance such as an original order confirmation or receipt
- the price appears unrealistically low
- several warning signs appear together
Counterfeiters may copy certificates, holograms, serial numbers, product photographs and even Icons.com gift boxes. Familiar branding should never replace careful research and due diligence.
The strongest items are those where every part of the package supports the same story. The autograph looks genuine, the underlying item is authentic, the certificate and holograms are consistent with genuine examples, and the provenance is credible.
If the evidence doesn't add up, walk away. There will always be another genuine item, but recovering your money from a counterfeit purchase is often far more difficult than finding the next authentic one.
