An investigation into the authenticity of Pokémon playtest cards has revealed that many of them were likely printed in 2024, rather than in the 1990s as previously believed. The discovery was made by analyzing the tiny yellow dots, known as tracking dots, that are printed on the cards by home and office printers. These dots can be decoded to reveal information about the printer and the print date. The findings suggest that some of the cards may be counterfeit or reproductions.
