COMC is thrilled to announce a new partnership with TAG (Technical Authentication & Grading), bringing TAG’s cutting-edge, technology-driven grading solutions directly to the COMC platform.
With millions of raw cards already available on COMC, this integration will expand your grading options and introduce a modern, data-rich way to grade, combining COMC’s marketplace convenience with TAG’s transparent, automated grading technology.
TAG + COMC: A win for collectors
Automated & data-driven grading
TAG’s patented computer-vision and imaging technology delivers data-backed results using a precise 1000-point scale, ideal for collectors seeking detailed, reliable assessments. The 1000 point scale enables each card to be precisely ranked on its TAG Leaderboard, where collectors around the world compete for the highest graded Scores of each card.
Full transparency & data-rich details
Every TAG-graded card includes a comprehensive Digital Imaging & Grading (DIG) report, downloadable high-resolution slab images, and (on select service tiers) 360° video. Buyers and sellers can review a card’s condition with total clarity before making a move.
Broad card-type support
TAG currently grades a wide range of trading cards — sports, TCG, and entertainment — and continues to expand its coverage of modern-era releases. (https://taggrading.com/pages/currently-grading)
