THE EUROPEAN GAMING REVOLUTION
Grading is a cultural act of historical preservation.
It is not just about protecting an object. It is about freezing a piece of video game history so it can travel through time: an independent judgment, a grade on a public scale, a seal nobody can alter. Born in 1949 with American coins, the method moved on to comics and cards, reached video games in 2008 and within a few years was hitting a million dollars at auction. Since 2025 TGMGrading has brought it to Europe, with an X-ray scan that sees inside sealed titles.
