The Future of Grading

Over a decade in the making, Technical Authentication & Grading is finally here.

To use innovation, to apply technologies, and to create for each collector:
transparencyaccuracy, and consistency for every card graded.

Submission Kits

After selecting what cards you want to submit, TAG will send all the complimentary supplies you need to properly protect your cards in transit. Submission Kits include TAG Shields, Easy Pull Penny Sleeves, TAG Rigid Deck Boxes, our securely cable tied TAG Safecase, and convenient, pre-paid express shipping.

Digital Reports

Every TAG graded card includes a detailed Digital Imaging & Grading Report (DIG). 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, Leaderboard, Chronology, and more.

Grading Technology

Our multi-patented technological grading system scores on a precise 1000 point scale & translates into an industry standard 1-10 Grade. Using Photometric Stereoscopic Imaging, TAG offers an unparalleled level of grading accuracy. TAG aims to represent the objective standard for collectible card grading.


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. All verified by OCR and our Card ID department.


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


TAG uses a UV and abrasion resistant thermoplastic acrylic with the highest clarity optics available. You have to see it for yourself to believe it.


Designed with radiused edges to maximize in-hand comfort and maintain extreme durability. The slabs also interlock and stack easily.

​TAG believes the card's appearance should speak for itself.
Say goodbye to distracting paper flips. Instead, the TAG grades
and data are permanently UV cured directly onto the slab.


Each card receives a 1-10 industry standard grade determined by its precise 100-1000 point TAG grade.


With a precise, 1000 pt TAG Grade, collectors can further differentiate grades, ie, a "high 10" from a "low 10." This allows cards to be ranked on the TAG Leaderboard.


Scan the TAG Grade to easily view the cards defects, hi-res images, scoring, centering, pop, rankings, & chronology via smartphone or web.


Scan the TAG Grade to pull up any cards Front and Back grades, subgrades, centering metrics and more via smartphone or web.

We Take Pride in Our Patents

Meet the Founder & CEO

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...
