GoldGrade began as a single collector’s obsession with finding the last factory-sealed copies of the games that defined a generation. Twenty-two years later we operate as the United Kingdom’s most exacting grading house for sealed Game Boy, Nintendo DS, PlayStation and contemporaneous platforms.
Each piece is examined in a controlled environment, photographed under standardised lighting and assigned a numeric grade. The certificate travels with the game forever.
“A GoldGrade certificate is the difference between a curiosity in a drawer and an asset on a wall.”— the GoldGrade ethos
