Digital Reports

Detailed Images & Reporting
Every TAG graded card includes a detailed Digital Imaging & Grading Report. By scanning the TAG Grade on the slab with your smartphone, instantly access high res images of all the identified defects, scoring breakdowns for individual card attributes, population, and unique features to be revealed soon. 

Completely Transparent.

Introducing the first ever “transparent flip,” otherwise known as the “tag." Our tags are as transparent as our grades: each includes a precise 1000 point TAG Grade and an industry equivalent, standard 1-10 roll-up Grade.


All necessary metrics for identifying a card including name,
year, set, card #,
and variations.


TAG uses a UV and abrasion resistant thermoplastic acrylic with the highest clarity optics available. 


With a precise, 1000 pt TAG Grade, collectors can further differentiate grades, ie, a "high 10" from a "low 10."


Digital security measures are embedded in every slab. Use your smartphone to instantly verify TAG authenticity.

Meet the Founder

After sixty-five years of collecting sports memorabilia, including over 400,000 cards, my son asked me a question which prompted a 10-year endeavor that would become TAG: “Dad, I know they mean a lot to you, but have you ever considered selling them?”

I had never sold a card and had no idea how to do it. At five years old, I purchased my first card using my own money earned doing chores-- a Wally Westlake ’51 Redbacks. Since that time, I acquired a lot of cards, many of considerably more value but none more cherished by me...
