ID Grader vs TAG
Updated April 21, 2026
How ID Grader's instant AI pre-grade stacks up against Technical Authentication & Grading — and why most serious collectors use both.
The short answer
ID Grader and TAG solve different problems. TAG is a professional third-party grading company that physically inspects your card, assigns an official grade, and seals it in a tamper- evident slab. ID Grader is an AI-powered pre-grade app you run on your phone in seconds — before you decide whether to submit anywhere.
Head-to-head
| Feature | ID Grader | TAG |
|---|---|---|
| Cost | $1.99 per scan or less in bundles | Tier fees comparable to PSA, with every submission including a detailed computer-vision report at no extra cost. |
| Turnaround | Seconds | Faster than PSA on most tiers — measured in weeks rather than months. |
| Physical slab | No | Yes |
| Signature authentication | Yes, AI verdict against an exemplar library | Varies by tier / separate service |
| Sub-grades | Centering, corners, edges, surface — always returned | Depends on service tier |
| Best for | Screening cards before submission, pricing raw cards, building a collection database | Collectors who want algorithmic, reproducible grades with a publicly viewable report instead of a human opinion behind a label. |
Where TAG wins
TAG is itself computer-vision-based. Every slab ships with a public report showing centering percentages, corner/edge/surface scores, and a 1,000-point composite — the most transparent grading report in the industry.
Where ID Grader wins
Instant verdicts, per-card cost measured in dollars instead of tens of dollars, no shipping, and built-in signature authentication that you can run at a card show before handing over money. Resale premiums still lag PSA. The TAG 10 market is growing but not yet as liquid.
The smart workflow
- Scan every submission candidate with ID Grader to get a full pre-grade in seconds.
- Only send the cards the AI rates a confident 9.5 or higher to TAG.
- Price or sell everything else raw with the AI sub-scores as evidence.
That single workflow change typically pays for ID Grader on the first submission batch you skip sending in.
