1. Why Pokémon Cards Are Worth Anything (And Why Most Aren’t)

The £300,000 Card That Convinced Everyone They Were Rich In 2021, a PSA 10 1st Edition Shadowless Charizard sold for more than £300,000. The story went everywhere. For a few months it was almost impossible to avoid headlines about six-figure Pokémon cards, and the predictable thing happened: people went up into their lofts and started […]

2. Grading and Condition: What Actually Separates a PSA 9 from a PSA 10

Grading and Condition: What Actually Separates a PSA 9 from a PSA 10 The Single Grade Point That’s Worth More Than A Car I own a Base Set Charizard. It isn’t 1st Edition and it isn’t Shadowless — it’s an ordinary unlimited print from 1999 that millions of people own. As a raw card it’s […]

3. Buying and Selling Pokémon Cards Online Without Getting Burned

It arrived. It was a Base Set Blastoise, and it was in a PSA slab. The grade was PSA 6. When I went back and actually read the description — which I should have done first — there it was, buried near the bottom: “Pictured card shown as example. Actual grade PSA 6.” The title […]

4. Why the Pokémon Card Market Goes in Cycles (And What That Means for Collectors)

The £20,000 Charizard That Became A £5,000 Charizard In early 2021, a PSA 10 Unlimited Base Set Charizard — not even the 1st Edition — was changing hands for somewhere around £18,000 to £22,000. Influencers were opening vintage packs on stream, the coverage was everywhere, and people who’d never owned a card in their lives […]

5. How to Store Pokémon Cards Without Quietly Destroying Them

The £500 Card I Ruined With A Binder I once owned a Near Mint Base Set Blastoise. Good centring, sharp corners, clean surface — worth perhaps £400 to £500 raw, and plausibly more than three times that if it graded well. Important: those figures are illustrative, not a current price guide. I kept it in […]

6. Are Pokémon Cards an Investment? An Honest Look at the Risks

Why Most Pokémon Card “Investors” Lost Money In 2020 and 2021, a great many people bought Pokémon cards as “investments”.

7. How to Spot a Fake Pokémon Card Before You Buy

The £800 Fake Charizard I Nearly Bought I was looking for a Base Set Charizard and found one listed at £750, against a market price of perhaps £900 to £1,000 at the time.

8. Sealed Products and Promos: What’s Worth Buying and What Isn’t

The £2,000 I Lost Opening Modern Booster Boxes Between 2020 and 2021 I bought modern sealed product as “investments” — Evolving Skies booster boxes, Shining Fates ETBs, Celebrations product, all on the received wisdom that “sealed always goes up”. I held them for a couple of years. By 2023 the same products were available at […]

9. What I Wish I’d Known Before I Started Collecting

Every Mistake In This Guide, I Made First When I started collecting in 2018, I worked through more or less the entire catalogue of errors this series describes. I bought fakes on eBay.
