How to keep a graded card collection safe

Card collecting has a security problem it didn't have five years ago. Graded slabs are small, valuable and easy to sell on, and thieves have noticed.

In October 2026, Dorset Police appealed for information after Pokémon cards worth about £10,000 were taken, along with a safe, a purse and cash, in one of a series of burglaries in West Moors (Dorset Police, October 2026). Earlier in the year, two brothers admitted burglaries at card shops in Warrington and Rugby that took more than £71,000 of stock (PC Gamer, 8 July 2026). And cards are at risk in transit too: in the US, police estimated that about $963,000 of cards sent for grading were stolen from a delivery truck in Santa Ana, California (ABC7 Los Angeles, 21 October 2026).

None of this means you should panic or sell up. It means a collection worth thousands deserves the same thought you would give jewellery or a watch. This guide covers the practical steps, most of which cost little or nothing.

1. Make your home a harder target

Most of this is ordinary burglary advice, applied to a collection that fits in a shoebox.

• Don't keep everything in one obvious place. A display cabinet in the front room, or a stack of slab boxes in the spare room, is the first thing a burglar finds. Split high-value slabs from the rest, and keep your best pieces out of sight.
• Use a safe that is bolted down. A small safe that can be carried away is a box with a handle. In the West Moors case the safe itself was taken. If you use one, anchor it to the floor or a wall, and choose one rated for the value inside it.
• Cover the basics. Good locks on doors and windows, a visible alarm, outside lighting and a doorbell camera all make a house less attractive than the one next door.
• Mind the packaging. Grading company boxes, branded envelopes and empty slab cases in the recycling tell people what is inside. Break them down and put them inside other rubbish.
• Keep displays modest. If you love showing your collection, display a few pieces you could bear to lose, or good printed photos, and keep the rest stored.

2. Be careful what you share online

Collectors share. That is half the fun. But public posts can tell a stranger what you own, roughly where you live and when you are away.

• Separate the collection from the address. Avoid photos that show your street, your house, a parcel label or a recognisable view from a window. Check the background of every photo.
• Turn off location tags on posts and strip location data from photos before you upload them.
• Think about timing. Police forces, including the PSNI and South Yorkshire Police, have long advised against posting that you are away until you are home. The same applies to "off to the show" posts.
• Keep the big pulls private, or post them later. Showing off a new slab the day it arrives at your door tells people exactly where it is.
• Use a separate collecting account with no real name, no hometown and no links to your personal profiles.
• Be wary of "can I come and see it" messages. Buyers who insist on collecting from your home, or want to know where you keep your cards, are worth a second thought. Meet in a public place, or use a shop.

3. Stay safe at shows and when travelling

Shows are where collectors and cards are most visible, and where a bag of slabs can disappear in seconds.

• Bring less. Take what you plan to sell or trade, not your whole collection.
• Keep cases on your body, not on the floor. A bag between your feet or on the back of a chair is an easy grab.
• Don't count stock in the car park. Put everything away inside the venue, and don't leave cases in a parked car, even for a few minutes.
• Travel with someone if you are carrying a lot, and vary your route home.
• Take card payments where you can, so you aren't walking out with a large amount of cash.
• Photograph what you take, so you know exactly what is missing if a case goes.

4. Document every card

If the worst happens, good records help the police, help your insurer and help you spot your cards if they turn up for sale. Dorset Police issued photographs of the stolen West Moors cards and asked anyone offered them to come forward, which only works when the photographs exist.

For each slab, record:

• Front and back photographs, in good light, with the label readable.
• The grading company, grade and certificate number. The certificate number is the single most useful identifier, because it is unique to that slab and can be checked on the grader's own website.
• What you paid, when and where, with receipts or screenshots of the sale.
• A current value, with evidence such as recent sold prices. Update it at least once a year.

Keep a copy somewhere other than your home, such as cloud storage or an email to yourself, so the records don't vanish with the cards. You can also register items free on Immobilise, the national property register UK police use to trace owners of recovered property.

5. Check what your home insurance actually covers

This is the step most collectors skip, and the one that costs most when it goes wrong. Home contents policies often cap what they will pay for any single item, and many treat a collection as one item.

Three examples from insurers' own public pages, checked on 29 October 2026:

• Admiral says "any item or collection worth more than £2,000 must be specified on your policy", and its list of high risk items includes "any collectible item which is rare or unusual" and "stamp, coin or other collections" (Admiral, high risk items).
• John Lewis Money says "anything above £3,000 in value will need to be specified on your policy" (John Lewis Money, valuables cover).
• Lemonade UK says collectibles are covered "up to the standard single-item limit" and that "collectibles and collections like trading cards can't be added as scheduled personal possessions" (Lemonade UK, updated 28 May 2026).

What this means in practice:

• Find your single item limit. It is in your policy schedule or wording, often under "valuables" or "high risk items". If a single slab, or your collection as a whole, is worth more than that limit, you may not be covered for the full value.
• Ask whether cards can be "specified". Specifying (sometimes called listing or scheduling) means naming an item and its value on your policy so it is covered above the standard limit. Some insurers will do this for cards and some, as Lemonade states, won't.
• Ask how a collection is valued. Is it one item or many? Do they want a valuation, and from whom?
• Ask about cover away from home. Taking cards to a show or a friend's house may need personal possessions cover.
• Ask about selling. If you sell regularly, some insurers may treat your stock as business stock, which a home policy may not cover.
• Consider a specialist. Collectibles insurers and brokers exist. Get the answer in writing either way.

Tell your insurer the truth about what you have. A claim on cards you never declared is the claim most likely to be refused.

6. Consider storing the best pieces away from home

For some collectors, the safest place for a valuable slab isn't the house at all. Options include a bank safe deposit box (if you can still find one locally), a storage service run by a card shop, or professional card storage.

Whichever you look at, ask the same questions:

• Who holds my card, and where? You should be able to name the business and the person responsible.
• Is it sealed, and how would I know if it had been opened?
• How often is it checked, and can I see proof?
• What does their insurance cover, and up to what value per card? Ask to see it. A business having insurance doesn't automatically mean your card is covered.
• How do I get my card back, how long does it take and what does it cost?

Whatever you choose, the steps above matter more: keep fewer cards at home, share less online, record every slab and know your policy.
