Our Diamond label identifies flawless cards in the top 1% of the grading scale. Highlighted by a premium silver label, it’s the ultimate way to showcase the crown jewel of your collection.
Grade Shade is the next evolution in premium card protection, and Mint Authentication leads the industry by integrating this advanced UV blocking technology directly into every slab. When grading sports cards, trading cards, TCG cards, and autographs, your slab should do more than display a label, it should preserve color, prevent fading, and shield your collectibles from harmful UV rays and ambient light. Grade Shade ensures long-term protection so your cards stay vibrant whether on display or stored away.
