GAI Grading Services
Global Authentication Inc. Established US grading company known for vintage and pre-war card authentication. Offers both card grading and autograph authentication.: Professional Sports Card & TCG Grading Standards
Market Analysis: GAI
Emerging / Boutique: As a newer entrant (Est. 2001), GAI 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
Analog Legacy: GAI relies on the traditional 'Human Expert' model. Three or more professional graders review the card under magnification. This approach is favored by vintage collectors who value 'Eye Appeal' over rigid mathematical perfection. Using a 1–10 scale, they evaluate cards based on the four core subgrades. Operating in the heart of the hobby, GAI competes directly with industry titans. To succeed here, they focus on aggressive turnaround times and competitive bulk pricing.
