ID Grader vs ISA
Updated April 21, 2026
How ID Grader's instant AI pre-grade stacks up against International Sports Authentication — and why most serious collectors use both.
The short answer
ID Grader and ISA solve different problems. ISA 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 | ISA |
|---|---|---|
| Cost | $1.99 per scan or less in bundles | Mid-range pricing that slots between GMA and SGC. |
| Turnaround | Seconds | Generally faster than PSA. |
| 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 | Mid-value sports cards where you want a faster, cheaper alternative to PSA without jumping all the way down to GMA. |
Where ISA wins
Transparent, half-point grading scale with clear sub-grades.
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. Smaller brand recognition — resale premium is below PSA, BGS, and SGC.
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 ISA.
- 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.
