About GraderIQ
GraderIQ was born from a moment every collector knows too well.
A card that had to be a 10 came back an 8, and the slab tax made it sting even more. Before every submission, it was the same ritual: FaceTimes, living-room debates, hopeful eyes convincing themselves this one was perfect. Then came the wait, 45, 60, even 90 days, only to open the slab and feel that gut punch.
After enough of those moments, grading stopped being fun. It became stressful.
As lifelong collectors, we felt that frustration firsthand. We searched for tools to help us understand our odds before sending cards in, but everything felt like guesswork. No transparency. No probabilities. No real insight.
So we built what didn’t exist.
Our founder taught himself to code, dove into machine learning, and created a system that analyzes the front and back of a card to deliver real, data-backed grading estimations. What started as a tool for friends quickly became something bigger.
GraderIQ exists to give collectors clarity and confidence. Scan your card, see the odds, and make smarter decisions.
