Authentication
Counterfeits have improved considerably, particularly on vintage Pokémon and Yu-Gi-Oh!. Here are the checks you can run yourself, and what a photo can and cannot settle.
In short
The most reliable authenticity checks on a collectible card are: the light test (most genuine cards contain an opaque inner layer that blocks light from a lamp placed behind them), examining the print rosette under magnification (counterfeits often show an irregular or blurry dot pattern), comparing font and text positioning against a known-genuine copy, surface texture, and cut regularity. A photo analysis flags visible anomalies but does not replace these physical tests.
Checks you can run yourself
Hold a lamp behind the card. A genuine card has an inner layer that largely blocks light; many counterfeits let noticeably more through.
Under magnification, genuine printing shows a regular dot pattern. Counterfeits often show a blurry, irregular pattern or dots of uneven size.
Compare font, stroke weight and exact text positioning with a copy you trust. Fakes are often off by fractions of a millimetre.
Surface texture, gloss level and corner cut regularity are hard to reproduce exactly.
What a photo analysis can do
Colour drift, misaligned text, atypical cutting, visibly coarse printing: these show up in the image.
Definitive authentication requires physical examination: light test, thickness measurement, magnification, sometimes substrate analysis. That is exactly what a grading company sells.
Frequently asked questions
Which cards are most counterfeited?
High-value vintage Pokémon (Base Set Charizard above all), Yu-Gi-Oh! 1st Edition, Magic's Power Nine, and five-figure sports rookies. The rule is simple: the higher the value, the higher the risk.
Can a graded card be fake?
A sealed slab from a recognised company is the best guarantee available, but slabs themselves are sometimes counterfeited. Always check the certification number in the company's online database and compare the recorded photo with the card in front of you.
Is the light test 100% reliable?
No. It eliminates most crude counterfeits, but the best fakes now reproduce the inner layer. It must be combined with the other checks.
