Market Analysis: Gradd
Emerging / Boutique: As a newer entrant (Est. 2022), Gradd offers specialized services often missed by major graders. However, collectors should be aware that secondary market liquidity is still developing. These slabs are best suited for 'Personal Collection' (PC) preservation rather than short-term flipping.
Technology & Protocol
Digital-First Hybrid: While grading may involve human review, the slab is built for the modern era. Integrated QR/NFC chips allow collectors to instantly scan the slab to verify provenance and view high-res scans, combating the rise of counterfeit slabs. Using a 1–10 scale, they evaluate cards based on the four core subgrades. By serving the Brazil market locally, Gradd safeguards collectors from the risks of cross-border shipping, providing a secure regional hub for authentication.
