What is the light test for Pokémon cards?

Hold the card up to a bright light. Genuine cards have an opaque black layer in the middle of the cardstock, so little light passes through. Fakes lack this layer and let light shine clearly through — it's the fastest, free authenticity test.

How do I verify a graded Pokémon card?

Graded slabs from PSA, CGC or Beckett carry a certification number you can look up on the grader's official site, which confirms the card and grade. This is the strongest verification for valuable cards.

Are 'Chinese' Pokémon cards fake?

The cheap bulk 'Chinese' cards sold in big lots are typically proxies/counterfeits, not official product. Official Pokémon cards are printed under license and pass the light, print-pattern and texture tests above.

Pokémon Cards Serial Number Check — How to Verify a Pokémon Cards (2026-06-26)

RealCheck › Collectibles & cards › Pokémon Cards serial check

Read the code

The Pokémon Cards set symbol + collector number (not a serial)

Set symbol + collector number (not a serial)

Format: Genuine cards carry a set symbol and a collector number in the bottom corner (e.g. '058/198') plus the set's regulation mark and a copyright line. There's no per-card serial, but the collector number must EXIST in that set and match the card's rarity symbol (circle/diamond/star).

Where to find it: Bottom-left or bottom-right corner: collector number, rarity symbol, set symbol, copyright.

How to verify (honest): There's no online 'serial lookup' for ordinary cards — but you can verify the collector number and set against an official set list. Graded slabs (PSA/CGC/Beckett) carry a cert number you CAN verify on the grader's site, which is the strongest authentication for valuable cards (and what eBay's Authenticity Guarantee covers for graded cards).

Don't stop at the code

A serial alone never proves authenticity

A correct-looking code on a poorly-made item still means fake — and fakers copy valid codes. Cross-check the code against the physical tells below.

What to check	Genuine	Fake
Light test	Hold the card to a bright light: genuine cards have an opaque black ink layer sandwiched in the cardstock, so very little light passes through.	Light shines through clearly — fakes lack the central black layer. The single fastest test.
Print pattern (loupe)	Under magnification the artwork shows a fine CMYK rosette dot pattern.	A coarse, lined, or blurry dot pattern — telltale of a low-res reprint.
Texture & cardstock	Correct stiffness and snap; holo/reverse-holo texture matches the era; the card has a slight blue tint on the back layer.	Too glossy or too flimsy, a back that's too dark blue or off-color, a 'slippery' feel.
Font & spacing	Crisp text, correct HP/energy-symbol placement, accurate fonts and the right copyright year.	Slightly wrong font weight, fuzzy text, misplaced HP or energy symbols, wrong copyright.
Weight & edges	Standard weight (~1.7–1.8 g); cleanly cut edges with no fuzzy/white edges on a black-bordered card.	Off weight, rough or white-edged cuts, or color bleeding at the border.
