Several steps to identify fake English Pokémon cards

The whole collectibles industry is fighting more and more convincing fake Pokémon cards. In its 2025 fraud report, PSA said it intercepted around $200 million in projected market value of fraudulent collectibles — and called that a conservative number, because valuing every fake at gem-mint prices would push it past a billion. Counterfeit and altered cards were up 45.3% year over year. Pokémon alone was up 125%, against 5.1% for sports cards.

Collectors buy these cards without knowing, on eBay, Mercari and Etsy — and on marketplaces where replica and “proxy” cards are listed openly, it is easy to end up with one that was never sold as genuine in the first place. With today’s printing, almost any card can be faked well enough to pass a listing photo.

The good news: fakes still fail on the things that are hard to copy — the holo, the paper, the ink and the fonts. Here is what to look at.

The most faked Pokémon cards from the original series

Unsurprisingly, the most faked cards are the most valuable ones. PSA’s list of the ten most counterfeited cards is six Pokémon and four sports, and Charizard sits at number one (EX and Base Set 1st Edition). Pikachu and Latias & Latios GX follow.

When it comes to Base Set, Charizard gets the headlines, but the whole holo line is a target. After Charizard, the ones you will see faked most often are the big names — Blastoise, Venusaur, Machamp, Mewtwo, Alakazam and Gyarados. Pikachu is copied constantly as well, despite being a common: it is the most recognisable card in the set, which is exactly the point when the buyer is a beginner.

The simplest starting point is to know what your card is worth, since value is what draws counterfeiters in the first place. You can browse the full Base Set sorted by value on PriceCharting.

The card at the centre of it all is the 1999 Base Set Charizard #4/102 Holo. Before you compare anything, work out which version you are actually holding — because this is where most people go wrong. They compare a genuine card against a photo of a different printing and talk themselves into believing something is fake.

Collectors usually talk about three tiers, but the English Base Set was actually printed more times between January 1999 and 2000:

  • 1st Edition — the first run, carrying the “Edition 1” stamp below and left of the art box. Shadowless template. The most valuable.
  • Shadowless — the same first run, just never stamped. No drop shadow to the right of the art box, brighter artwork, thinner HP and attack text.
  • Unlimited — the drop shadow appears, and the HP and attack text gets thicker. Unlimited was itself printed six times, and those runs are, for practical purposes, indistinguishable from one another.
  • ©1999–2000 — the final run, identified by the copyright line carrying both years instead of just 1999.

Language matters too. There are Japanese, English and other regional printings, and their fonts, layouts and stock are not interchangeable — a “tell” from an English card proves nothing about a French one. In this blog post we are focusing on English cards. The practical takeaway: identify the printing first, then compare.

One trend worth knowing: counterfeiters have started faking cheaper cards, betting that a $40 card gets less scrutiny than a $4,000 one. Do not skip the checks just because the card is not expensive.

Common errors in fake Pokémon cards

In general there are several things you can spot on a card that tell you it is fake. A good rule of thumb is to compare the card against a genuine one — which is why we built a comparison tool into the Guredo mobile app.

1. Text sizing. Type that is slightly too large or too small compared to a genuine card from the same set. You will usually only see it side by side.

2. Wrong font. Most often in the card name, the HP, or the attack text. Counterfeiters rarely have the exact typeface, so letters end up a little too bold, too wide, or spaced unevenly.

3. Holo effect. Missing entirely, or the wrong pattern. Base Set holos have a specific star-flecked look — a smooth mirror sheen or a rainbow film is wrong.

4. Texture pattern. Missing, wrong, or present on a card that should be flat. Run a fingernail across the artwork: a genuine holo has a subtle, even texture.

5. Energy symbols. A very common tell. The symbol inside the circle is often oversized, off-centre, or the wrong shade.

6. Paper layers. A real card is a sandwich: front paper, a black core layer, back paper. Look at the cut edge straight on and you should see a dark line running through the middle — it reads almost like three layers. Most fakes are printed on two-layer stock and show a grey or blue-ish line, or none at all. The Poké Master Center walkthrough shows this clearly.

7. Back-side colour. Genuine backs have a dappled mix of light and dark blue with a crisp boundary between the swirl and the outer frame. Many fakes wash out to one flat, slightly purple blue.

8. Rosette printing pattern. Under a 10x–30x loupe, real cards show a regular dot rosette — the signature of professional offset printing. Flat colour, random dots, or a coarse grid means it came off the wrong kind of press. Check the yellow border and the blue back, where the pattern is easiest to read.

9. Misspellings and typos. A missing accent — “Pokemon” instead of “Pokémon” — wrong HP, or broken grammar in the attack text is a near-certain fail. Real cards go through proofing; fakes often do not.

10. The 1st Edition stamp. On stamped cards, check the “1” itself: wrong stroke thickness, blurry edges, wrong size, or sitting slightly off position. It is a small mark and it is copied badly more often than you would expect.

11. Border sizes. Genuine cards are famously not perfectly centred, so off-centre borders alone prove nothing — that is a condition issue, not an authenticity one. What matters is borders that are wildly uneven, or a cut that wanders along the edge.

12. Weight. A standard Pokémon card weighs roughly 1.8 g. A holographic card from the Base Set can weigh up to 2.24 g. Some modern non-holo cards weigh around 1.9 g, and a modern holo a little more, about 1.95 g. Reverse holos weigh between 1.8 g and 2 g depending on the set and series, and the same goes for full arts.

13. Overall quality. Trust your hands. Fakes often feel flimsy or unusually stiff, have a glossy coating the real card does not have, or show soft, rounded corners straight out of the pack.

14. Error and misprint cards. Something being wrong with a card does not automatically make it fake. Errors happen during printing, and there is a whole subreddit devoted to them.

1, 2 and 9. Wrong font size, wrong font style and a misspelling on the Farfetch'd card on the left. The left card is fake, the right one is authentic.

A few examples of fake Charizard cards

Let’s look at a few examples of fake Charizards. One of the most common giveaways on a Base Set card is a holo that matches the official scan on tcgplayer.com perfectly. That is a strong indicator the card is fake, because the pattern of holo stars on a Base Set card is unique to that individual copy — on an authentic card the stars sit in different positions.

How to check that your TCG card is authentic

  • Compare against the community. Post the card and let collectors who own the same printing tell you what looks off. A second pair of eyes catches what a single check misses.
  • Compare against a database. Match your card to confirmed genuine and confirmed fake examples of the same set, printing and language — the comparison is what makes a tell obvious.
  • Use your camera and AI. Photograph the front, back and edge, and let the analysis score the print pattern, texture and layer structure for you.

In short

No single check proves a card is fake. Work through several of them and look for a pattern. Start with the ones that cost nothing — hold the card to the light, look at the cut edge for the dark core layer, feel the texture, read the text for a missing accent on “Pokémon”. Then reach for a loupe and a scale if something still feels off. Above all, compare against a card you know is real, from the same set, the same printing and the same language, because most tells only become obvious side by side. And if two checks disagree with each other, that is your answer: slow down and ask someone before the money moves.

Next up, we will do the same for GX cards — a much newer generation, with its own set of common fakes and its own giveaways in the foil, the texture and the card back.
