The trading card market has experienced significant growth over recent years, driven by increasing demand for products such as Pokémon, One Piece, Magic: The Gathering, Yu-Gi-Oh!, sports cards and other collectible trading card games. Alongside growing popularity has come a substantial increase in the value of sealed products, graded cards and other associated collectibles.

Unfortunately, this rise in demand and value has also made trading card retailers, online sellers, market traders and distributors increasingly attractive targets for criminals. Reports from across the hobby indicate that thefts from retail premises, warehouses, storage units, vehicles and even private residences used for business purposes are becoming more common. Criminals are often well-informed and specifically target products they know can be quickly resold for significant sums.

As a result of this, businesses operating within the trading card sector should take proactive steps to protect their stock, minimise loss potential and ensure they are adequately insured.

Why are trading cards attractive to criminals?

Unlike many traditional retail products, trading cards possess characteristics that make them particularly vulnerable to theft:

Small, portable and easy to conceal
High value relative to their size
Easily sold through online marketplaces, social media channels and private sales
Difficult to trace if accurate records are not maintained.
Prices can fluctuate significantly in a short period, particularly following new releases, tournaments, media announcements or grading population changes

A single box of cards or a handful of rare singles can represent thousands of pounds in value, making trading card businesses an increasingly attractive target.

In each of the below headings, we’ve provided advice and tips for you around all matters of insurance. Click the read.

Physical Security Measures

Secure Premises

Retailers should review the physical security arrangements protecting their premises, especially outside trading hours. Recommended measures include:

  • Monitored intruder alarm systems.
  • High-quality locks meeting current security standards.
  • Reinforced doors and shutters.
  • Secure display cabinets for valuable singles and graded cards.
  • CCTV systems covering all entrances, exits, sales floors and storage areas.
  • External lighting with motion detection.
  • Restricted access to stock rooms and storage areas

Visible security measures can often act as a deterrent and reduce the likelihood of opportunistic theft.

Night-time and out of hours security

Many thefts occur when premises are unoccupied.

 Businesses should:

  • Remove higher value stock from shop floors overnight, if possible.
  • Store valuable inventory in safes or secure locked storage.
  • Avoid leaving premium products in visible areas.
  • Ensure alarm systems are tested regularly and consider having an alarm system installed which reports directly into a monitoring service and/or provides a Police response.
  • Verify CCTV systems are recording correctly and footage is retained for an appropriate period.

Where substantial quantities of high-value stock are held, a professionally installed security safe or strong room may be worth considering.

 Protecting stock in transit

Stock is often most vulnerable when being transported between suppliers, events, exhibitions, storage locations or retail premises.

To reduce risks here:

Never leave stock unattended in vehicles. Where stock has to be unattended, ensure the vehicle has sufficient internal and external security such as external locks and internal fixed storage cages.

  • Avoid any advertising hinting at the nature of goods being transported and use unmarked vehicles where possible.
  • Plan secure routes and minimise unnecessary stops
  • Load and unload stock discreetly.
  • Consider GPS tracking for high-value shipments.
  • Consider your local environment – is anyone shadowing you or loitering?
  • Use reputable specialist couriers for valuable consignments

Many losses occur within minutes when stock is left unattended in vehicles, even briefly

Inventory Control and Record Keeping

One of the most important safeguards following a theft is the ability to accurately identify and evidence what has been stolen. Businesses should maintain:

Comprehensive Stock Records

  • Product descriptions
  • Quantities held
  • Purchase invoices
  • Supplier details
  • Purchase values
  • Current market values where applicable

Photographic Records

Photographs can significantly assist police investigations and insurance claims. Particular attention should be given to:

  • Graded cards
  • High-value singles
  • Limited-edition products
  • Sealed cases and collections

Where possible, record:

  • Certification numbers
  • Serial numbers
  • Grading details
  • Distinctive markings

Regular stock audits

Frequent stock counts help identify discrepancies quickly and may reveal thefts before substantial losses occur. Regular auditing also ensures that stock valuations remain current and accurate.

Staff awareness and internal controls

Not all theft originates externally. Businesses should:

  • Restrict access to high-value inventory
  • Use secure stock management systems.
  • Implement dual-control procedures for valuable stock movement.
  • Review CCTV footage when discrepancies arise
  • Conduct regular staff training on security protocols
  • Establish clear procedures for opening and closing premises

Strong internal controls can significantly reduce both internal and external theft risks.

The Importance of adequate insurance

As trading card values continue to evolve, businesses should pay particular attention to their insurance arrangements. Many trading card products can appreciate rapidly due to:

  • New product releases
  • Tournament results
  • Media exposure
  • Changes in rarity or availability
  • Market speculation and collector demand

A stock valuation that was accurate just a few weeks ago may no longer reflect today’s replacement cost.

Avoiding underinsurance

Underinsurance occurs when the sum insured is lower than the actual value of stock held. This can create significant problems following a claim. In many cases, insurers may apply the principle of average, meaning that if stock is only partially insured, claim settlements may be reduced proportionately. For example, if a business is insured for £100,000 of stock but is actually holding £200,000, any claim payment will be reduced proportionate to the level of underinsurance in play, in this case 50%, leaving you with a payout of just £50,000.

Regular insurance reviews

Businesses should:

  • Regularly assess current stock valuations
  • Notify insurers of significant increases in stock levels
  • Review seasonal stock fluctuations
  • Consider peak trading periods
  • Ensure temporary stock increases for major releases or events are disclosed
  • Maintain accurate stock records to support declared values

Insurance should reflect the realistic replacement cost of inventory, not simply the historical purchase price.

Should a theft occur… 

Despite best efforts, thefts can still happen. Businesses should:

  1. Contact the police immediately, obtaining a Police reference number for the incident.
  2. Preserve CCTV footage and alarm records
  3. Avoid disturbing potential evidence
  4. Compile a detailed inventory of stolen items
  5. Gather photographs, serial numbers and purchase documentation
  6. Notify insurers as soon as possible
  7. Inform relevant marketplaces and industry contacts where appropriate
  8. Monitor online sales channels for stolen items being offered for sale

Having detailed records readily available can significantly improve recovery efforts and streamline the claims process.

Conclusion

The growth of the trading card hobby has created exciting opportunities for retailers, vendors and commercial sellers. This, however, has increased demand and rising values and therefore attracted criminal attention. By investing in robust security measures now, maintaining detailed stock records, protecting inventory in transit and regularly reviewing insurance arrangements, trading card businesses can place themselves in a much stronger position to prevent losses and recover more effectively should a theft occur. Just as importantly, businesses should regularly review their sums insured to ensure cover keeps pace with the rapidly changing value of trading card stock. Adequate insurance, combined with strong risk management practices, remains one of the most effective ways to protect both inventory and the long-term health of the business.
