Found Your Old Pokémon Cards? Here’s What To Do Next

This article is written for beginners who have just rediscovered their old Pokémon cards and want to know how to protect, value, or sell them.

That shoebox in the attic might be worth more than you think

It happens all the time. You’re clearing out a drawer or loft and stumble across a pile of old Pokémon cards from your childhood. Maybe you spot a Charizard, a Pikachu, or even some first edition cards you’d forgotten about. The nostalgia kicks in, followed quickly by the big question – what are they worth, and what should you do next?

The good news is that your find could be more valuable than you expect. The Pokémon trading card market has grown massively in recent years, and collectors across the UK are constantly searching for well-kept vintage cards. But before you rush to sell, there’s an important first step – getting your cards graded.

Why grading is the key to unlocking real value

Grading means sending your cards to a professional card grading company like Majesty Grading Company (MGC), who will carefully assess the condition, authenticity and presentation of each card. Once graded, your cards are sealed in tamper-proof holders, complete with a serial number and grade that confirm their authenticity and quality.

Having graded Pokémon cards makes selling far easier. Buyers trust the grade and are willing to pay more because they know exactly what they’re getting. It also protects your cards long-term – no more scratches, bends or fading from old binders.

MGC has become the number one choice for Pokémon card grading in the UK, known for its fast turnaround, transparent process, and precision in every grade. Thousands of collectors – from casual fans to serious investors – have already discovered how grading turns nostalgia into opportunity.

Real collector stories – and how grading changed everything

To show what’s possible, here are a few examples inspired by real MGC customer experiences:

1. Tom’s forgotten Charizard collection

Tom, 32, from Manchester, found a binder of Base Set Pokémon cards while visiting his parents. “I nearly threw them away,” he laughed when speaking to us later. He decided to get his Pokémon cards graded with MGC, including a Charizard that came back an MGC 9. The card later sold through one of our auction partners for just over £800 – more than enough to fund his next collection goal.

2. Emma and her son’s discovery

Emma, a parent from Reading, submitted her son’s cards after hearing about MGC from another collector. They wanted to see what grades they might get and were amazed when a couple of full-art Pikachu cards came back MGC 10s. Rather than sell, they chose to keep them as keepsakes – a graded time capsule of her son’s childhood collection.

3. Alex the weekend flipper

Alex, 25, started grading with MGC after finding his old XY-era cards. He joined the MGC Membership programme for discounted grading and began sending batches each month. Within six months, he was flipping graded cards through eBay and WhatNot, using his profits to buy sealed boxes to collect and open live. “Grading gave me credibility as a seller,” he said. “Buyers trust MGC slabs, and that makes selling a lot easier.”

Thinking about selling your Pokémon cards?

Once you’ve graded your cards, you have a few ways to sell them:

• Through MGC’s auction house partners – the simplest and safest option. Our auction partners specialise in high-quality collectibles and reach thousands of serious buyers, ensuring your cards achieve fair market value.
• Sell them yourself – platforms like eBay or WhatNot are popular, but come with risks. Unverified buyers, fake payment claims, and lowball offers are all too common. If you choose to sell privately, protect yourself by:

• Using tracked and insured shipping.
• Avoiding direct deals outside the platform.
• Checking a buyer’s feedback and history before agreeing a sale.
• Photographing your graded cards before shipping – showing serial numbers clearly.

Graded cards not only sell faster but also protect you as a seller. The encapsulation proves authenticity, and buyers can verify the serial number using our upcoming Cert Lookup tool.

How to start grading with MGC

Submitting your cards is simple. Visit the Submit Items page and select the category for your cards. Choose the service speed that suits you – Bronze (2-8 weeks), Silver (14 days), or Gold (3 days). Then create your account, list your cards, print your form, and send them securely. You’ll receive updates at every stage, and when your cards return, they’ll be beautifully encapsulated, ready for display or sale.

If you’d prefer a hands-on approach, check out our Local Submission Hubs, where you can drop cards off in person through trusted partner stores.

From rediscovery to reward

Whether your goal is to keep your cards safe, see their true value, or sell for a profit, grading is the best next step. Every collector’s journey starts somewhere – and yours might begin with a forgotten binder and end with a graded collection worth showing off.

So before you sell or store those old Pokémon cards away again, let MGC help you unlock their potential. You might just be sitting on a hidden treasure.
