How TroCuri grades.

TroCuri grades cards on the PSA 1 to 10 scale using PSA's official, word-for-word grade definitions - and it is calibrated against 14 real PSA-graded reference cards, from PSA 1 all the way to PSA 10 (including half-grades and Authentic / Altered examples), so its eye is anchored to genuine professional grades rather than a guess. It scores the PSA Four C's - Centering, Corners, Edges, and Surface - plus print quality, color, and gloss. If a card is already slabbed (PSA, BGS, SGC, CGC, or HGA), TroCuri recognizes the holder and reads the grade off it instead of re-grading. Then it prices the card from real, recent sold comps.

Grading is one step of TroCuri, our in-house Listing Tools pipeline: it also identifies each item, scrapes recent sold comps, recommends a fair price, and composes the listing before a person reviews it.

What it looks at.

Centering - the border ratios front and back, against PSA's tolerances
Corners - sharp versus soft, dinged, or frayed
Edges - clean versus chipping or whitening
Surface - scratches, print lines, dents, or gloss loss
Print, color & gloss - plus slab detection (PSA, BGS, SGC, CGC, HGA)

The 1 to 10 card grade scale

10 Gem Mint - virtually flawless, razor-sharp
9 Mint - one tiny flaw at most
7 to 8 Near Mint to NM-Mint - minor wear on a close look
5 to 6 Excellent - light but visible wear
3 to 4 Very Good - rounded corners and surface wear
1 to 2 Poor to Good - heavy wear, creases, or damage

What you get on every listing.

An estimated grade plus notes on centering, corners, edges, and surface
High-resolution photos of the exact card, front and back
Cards are raw (ungraded) unless stated - our grade is an honest estimate, not a slab

AI-assisted, human-confirmed.

Our grades are careful in-house estimates that help us set fair prices and give you clear expectations. They are not a replacement for professional third-party grading such as CGC, PSA, or PCGS. When an item has been professionally graded, the listing says so. If there is a flaw, it is in the photos and the description.
