Benefits
Why use Gradeon for your card collection?
How Gradeon helps collectors, sellers and shops make faster, clearer and more consistent decisions.
Consistent pre-grades
Every card is scored on the same rubric: four sub-grades per side, with every defect marked on your photo. No mood, no guesswork.
Organized Collection
Save your scans to digitize your entire collection and sort your cards by grade, set, rarity, or value: you'll always know what you own and how much it's worth.
Save time & fees
Know which cards are worth submitting before you pay grading fees, and skip the back-and-forth when you buy, sell or trade.
Real-time value tracking
Follow your collection’s value with Cardmarket and TCGplayer prices, and see what each card could be worth at its estimated PSA tier.
Scan your way
Quick Price for an instant value, Full Grade for a complete pre-grade, Deep Analysis for a loupe-level pass, and Rapid Scan to work through a whole binder.
Built with collectors
Gradeon grows with feedback from its community. Every bug report and centering correction helps the next pre-grade get better.
