Counterfeit Detection Basics
Counterfeits target high-value cards with the highest expected EV. Detection: paper weight, microprinting, UV response, ink density, dimension, holo pattern.
The 6-test detection matrix
- Paper weight: weigh card on digital scale. Modern Pokemon should be 1.8-2.1g; counterfeits often 1.5-1.7g
- Dimensions: caliper check (modern standard 2.5" × 3.5")
- UV response: real cards have specific UV fluorescence; counterfeits often flat
- Microprinting: 10× loupe on tiny details (manufacturer logos, holo patterns)
- Ink density: real ink is uniform; counterfeit often patchy/banding
- Holo pattern: cosmic, lined, or alternative hologram pattern often wrong on counterfeit
Highest-risk targets
Cards counterfeited most often:
- WOTC Pokemon (Base Set Charizard #4)
- T206 Honus Wagner (most famous counterfeits)
- 1986 Fleer Jordan #57
- 1952 Topps Mantle
- Recent Pokemon Alt Art Charizard/Pikachu
- Yu-Gi-Oh 1st Edition Blue-Eyes LOB-001
When in doubt
Submit the card to PSA, BGS, CGC, or SGC for grading. Graders perform authentication as part of standard service. If the card is counterfeit, the grader returns it marked 'Authenticated, Not Genuine' or refuses to grade.
