TAG 9. TAG is an objective grading company not subjective like PSA.

How it Works: TAG (Technical Authentication & Grading) utilizes proprietary, patented computer vision technology that scans cards using high-resolution cameras and various lighting configurations (photometric stereoscopic imaging).

Objectivity: The AI analyzes centering, edges, and surface conditions to generate a "Digital Imaging & Grading" (DIG) report, providing a 1000-point score that is translated into an industry-standard 1-10 grade.

Human-in-the-Loop: While the machine generates the grade, human grading experts review the data and identify defects to ensure accuracy and consistency before the final grade is confirmed.

Transparency: Unlike traditional graders, TAG provides a detailed report (DIG report) for every card, showing exactly why a grade was awarded, including 800x zoomed images of identified defects.
