Counterfeit Card Detection: Sports and Pokémon Cards, Slabs and Certs
Practical checks for counterfeit sports and Pokémon cards and fake graded slabs: print pattern under magnification, card stock, fonts, light test, holograms and cert lookups.

Counterfeiters target expensive rookies, autographs and chase cards, and they increasingly fake graded slabs too. No single test is proof, so stack several checks and compare against a copy you know is genuine. For Pokémon-specific checks, see our Pokémon fake card checklist.
1. Look at the print under magnification
Factory-printed cards are made with offset printing. Under a jeweler's loupe (around 30× to 60×), the colors break into a regular pattern of tiny dots called a rosette. Many fakes are made on home or digital printers and show a different, fuzzy or irregular dot pattern, or blurry edges on text. Compare the same area on a genuine card from the same product.
2. Card stock, thickness and finish
Check the thickness, stiffness and gloss against a real card from the same set. Chrome-style sports cards have a distinctive metallic finish that cheap fakes struggle to copy. Pokémon cards have a layered stock with a dark inner layer that's often visible at the edge.
3. Fonts, logos and copyright lines
Compare the player name font, the card number, the manufacturer and league logos, and the fine-print copyright line. Misspellings, wrong years and slightly off typefaces are common giveaways.
4. The light test
Shine a flashlight through the card and compare it with a genuine card from the same era. Different light transmission is a warning sign, but treat it as a hint, not proof.
5. Serial numbers, autos and relics
For a numbered parallel, check that the serial stamp's font and foil match genuine examples. Autographs and relic windows should match the product's authentic style. Be extra careful with "1/1" claims.
6. Graded slabs and cert lookups
Always look up the certification number on the grader's own site, such as PSA cert verification or CGC cert lookup. Confirm that the card, year, number, grade and (where available) images match the slab in front of you. Then inspect the case: label printing, hologram, and any signs that the case was opened and resealed. PSA's published standards say it won't grade cards of questionable authenticity (its N4 code). A genuine slab shows the card passed that review, which is why fake slabs exist.
7. Buy smart
- Use platforms with buyer protection and keep all listing photos.
- Be wary of prices far below recent comps.
- For high-value cards, ask for extra photos (corners, back, cert) before you pay.
