AI Card Grader – Precision Meets Innovation
Combining advanced AI technology with expert human verification, SSINT delivers the most accurate and consistent card grading system in the industry.
ssint. AI GRADER
At SSINT, we are committed to pushing the boundaries of trading card grading. After years of research, investment, and AI model training, we are proud to introduce the SSINT AI Grader — launching in 2025.
This revolutionary system combines cutting-edge machine learning with expert grader oversight, offering collectors a level of accuracy, consistency, and transparency never before seen in the industry.
Why AI Grading Matters
The traditional grading process can be influenced by human subjectivity and natural inconsistencies. With AI, we remove bias and add precision.
✅ Faster grading turnaround
✅ Objective and consistent assessments
✅ Transparency in defect detection and centering
✅ Backed by human verification for collector trust
How the SSINT AI Grader Works
Step 1 – High-Resolution Scanning:
Each card is captured in ultra-high detail.
Step 2 – Dual AI Models:
Two AI models analyse the card independently, cross-verifying results to eliminate errors.
Step 3 – Defect Detection:
The system inspects corners, edges, and surface for whitening, scratches, or flaws.
Step 4 – Centering Precision:
Our centering tool measures alignment to a standard no human eye can match.
Step 5 – Expert Verification:
Every grade is confirmed by our professional grading team before it is finalised.
Defect Grading Methodology
SSINT cards are graded across three key areas:
🟦 Corners – sharpness and whitening
🟩 Edges – wear and consistency
🟥 Surface – scratches, print lines, and imperfections
Grading Formula:
Front Grade = Corner + Edge + Surface
Back Grade = Corner + Edge + Surface
Centering Grading
Centering is critical to a card’s overall grade. Our software engineers have designed the industry’s most accurate centering tool, with a weighted approach:
Centring Grade = (0.6 × Front Centering) + (0.4 × Back Centering)
This ensures the front alignment carries more influence while still accounting for the back.
Final Grade = (0.6 × Front) + (0.4 × Back)
This weighting ensures the front of the card carries more importance — just as collectors value it most.

Hybrid Approach – AI + Human Verification
At SSINT, we understand that while AI offers unmatched speed and precision, trading card grading is about trust and market value. That’s why we use a hybrid model — combining the objectivity of AI with the expertise of our professional graders.
How AI Works Best Under Human Oversight:
Error Minimisation: AI excels at detecting tiny imperfections, centering misalignments, and surface inconsistencies that might be missed by the human eye. Certain rare anomalies, like unusual print patterns or holographic effects, are better interpreted with human judgment.
Contextual Understanding: Collectors and the market value cards not just by flaws but by rarity, print variations, and overall eye appeal. Human graders provide the contextual knowledge that AI alone cannot fully grasp.
Continuous Learning: Every card reviewed by an expert becomes feedback for the AI, helping the system refine its accuracy over time. This creates a self-improving hybrid that gets better with every submission.
Trust & Transparency: AI provides objective measurements, but the final grade is validated by a trusted human grader, giving collectors confidence that the grade is both accurate and market-credible.
Individual AI Grading Report: Each card receives its own detailed AI report, highlighting any defects spotted, centering measurements, and preliminary scores for corners, edges, and surface. This allows collectors to see exactly how the AI assessed their card, even before expert verification.
Why This Hybrid Model Sets SSINT Apart:
⚡ Faster Turnaround: AI speeds up preliminary analysis.
📊 Consistent Results: No human bias or fatigue affects the initial evaluation.
🏆 Trusted Validation: Experts ensure every grade aligns with market expectations.
🔍 Enhanced Transparency: Detailed AI reports paired with expert notes allow collectors to understand the reasoning behind every grade.
In short, the SSINT hybrid approach combines the precision of AI and the experience of human graders, resulting in grades collectors can trust — with full visibility through a personalized AI grading report for every card.
