Built by a Collector. Driven by Integrity.

Integrity Grading Company (IGC) was founded in Oklahoma out of a genuine passion for sports card collecting.

What began with buying, selling, researching, and collecting sports cards grew into a deeper interest in the grading process itself. Through firsthand experience in the hobby, the idea emerged to create an independent grading company built around the values collectors appreciate most: accuracy, consistency, transparency, and trust.

That vision became Integrity Grading Company.

From developing grading standards and creating a sleek, professional presentation that collectors can appreciate to incorporating modern AI-assisted technology alongside human evaluation, IGC was built from the ground up with the collector in mind.

We’re a growing company with a simple goal: to build a respected name in the hobby by earning collectors’ confidence, one card at a time.

INTEGRITY. PRECISION. CONFIDENCE.
