How AI Pokémon Card Grading Works

The TCG CollectWorld grader gives any Pokémon card an instant estimated PSA grade from a single photo. It scores the same four sub-grades professional graders use — centering, corners, edges, and surface — then combines them into an overall 1–10 estimate plus projected PSA 8, PSA 9, and PSA 10 market values.

The four sub-grades explained

Centering measures how evenly the printed border sits around the card. The AI compares left-to-right and top-to-bottom margins; a 55/45 split front and 60/40 back is the practical PSA 10 ceiling for modern cards.

Corners looks for whitening, fraying, dings, and rounding. Even a single softened corner usually caps a card at PSA 9.

Edges checks the perimeter for nicks, chipping, and factory whitening. Holofoil and full-art borders are inspected at higher sensitivity because dark borders amplify defects.

Surface evaluates scratches, print lines, holo scratches, indentations, and dirt. This is the most subjective category at PSA, and where home graders most often disagree with the lab.

How the scoring is calibrated

Each sub-grade is returned as a 1–10 number with a short reason. The overall grade follows PSA's published logic: the lowest sub-grade dominates, but two sub-grades at 8 or below typically drop the overall by one full point. The estimated PSA 8/9/10 prices come from current TCG CollectWorld market data for the same printing, so a freshly scanned card lands on a real, comparable value range.

Where AI grading helps and where it doesn't

AI grading is fast, free, and consistent — it's ideal for triaging a binder, picking which cards are worth a real PSA submission, or checking listings before you buy. It is not a substitute for a sealed PSA slab: lighting, glare, sleeve haze, and camera focus all bias the score. For high-value modern chase cards, treat the AI grade as a guide and submit to PSA for the real verdict.
