Kayou & Card.Fun Grading in the UK: The Hidden Collectibles Market

The UK trading card scene has always been dominated by Pokémon, Yu-Gi-Oh!, and sports cards. But in recent years, Kayou and Card.Fun cards have rapidly gained popularity among collectors looking for something fresh, unique, and highly collectible.

Despite their growing demand, many grading companies in the UK ignore or undervalue these sets. At SSINT, we take a different approach — recognising Kayou and Card.Fun as legitimate collectibles worthy of the same security, attention to detail, and premium grading as any other trading card.

What Are Kayou and Card.Fun Cards?

  • Kayou Cards – Known for their vibrant designs and collaborations, Kayou has released hundreds of licensed sets that cover anime, gaming, and pop culture.

  • Card.Fun – Established in 2020, Card.Fun has partnered with over 100 licensors and produced 500+ co-branded cards, making them one of the fastest-growing trading card brands.

Both are gaining traction with UK collectors who want something beyond the mainstream, but grading options have been limited — until now.

Why Grade Kayou and Card.Fun Cards?

  1. Rarity & Licensing – With limited production and strong licences, these cards are valuable to niche collectors.

  2. Protection – Grading keeps their unique foils and finishes safe from scratches and fading.

  3. Legitimacy – A graded Kayou or Card.Fun card carries credibility in a marketplace still learning about these brands.

  4. Market Growth – These sets are on the rise, and early graded examples will benefit as demand increases.

How SSINT Supports Kayou & Card.Fun Collectors

  • Acceptance of All Sets – While some graders avoid them, SSINT openly grades Kayou and Card.Fun.

  • Laser-Engraved Aluminium Labels – Adds premium presentation and authenticity to your slab.

  • More Detailed Labels – SSINT includes more descriptive information about your card than any competitor.

  • UV-Protected, Ultrasonically Welded Cases – Prevent damage from light exposure or handling.

  • Case Options for All Thicknesses – Whether it’s a standard card or a thicker special edition, we have custom cases to fit.

  • Creative Legends Tier – For custom Kayou-style artworks or artist collaborations, SSINT can label the artist and handle.

The Missed Opportunity by Other Grading Companies

Most UK graders focus almost exclusively on Pokémon, Yu-Gi-Oh!, and sports cards. This leaves a massive SEO and collector gap around Kayou and Card.Fun content. By providing secure, detailed grading for these cards, SSINT is filling that gap and leading the way in supporting collectors of new, exciting brands.
