Market Analysis: TSG
Emerging / Boutique: As a newer entrant (Est. 2022), TSG 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: TSG 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. By serving the Taiwan market locally, TSG safeguards collectors from the risks of cross-border shipping, providing a secure regional hub for authentication.
