About SportGrading
Independent judgment for modern collecting.
We believe a great certification should make a card easier to understand—not harder to trust.
Our purpose
Clarity in a market built on details.
SportGrading exists to bring a measured, consistent voice to sports-card condition and authenticity. Our process is designed around evidence, repeatability, and a collector-first experience.
We are building the infrastructure for a certification record that can travel with a card across collections, transactions, and generations.
Our principles
- Evidence over excitement We document what the card shows.
- Consistency over guesswork The same framework applies to every submission.
- Transparency over jargon Standards are written for real collectors.
