TAG Grading System

TAG uses computer vision to assign 1-1000 sub-grade per axis. Publishes every score on the slab. Best for 'highest TAG' listing titles.

The 1000-scale

TAG scores centering, corners, edges, surface on 1-1000 (rounded to 10s). A card scores 950+ on all axes for TAG 10 (Pristine). Collectors can see if your TAG 10 is a 950 or a 998 — the 998 commands a unique listing premium.

Market position 2024-2026

• Modern Pokemon TAG 10 ≈ 0.6–0.9× PSA 10 (closing gap)
• Modern sports TAG 10 ≈ 0.5–0.8× PSA 10
• TAG 998+ titles outperform: unique 'highest TAG' premium

When to choose TAG

1. PSA 10 candidate but customer wants second-opinion data
2. Marketing the card as 'algorithmically verified'
3. Consigning to a TAG-promoting auction house
4. Expecting a sub-grade flaw and wanting transparency over ambiguity
