Who TAG is
TAG stands for Technical Authentication & Grading. Its founder and CEO, Steve Kass, describes on TAG's site a lifetime of collecting and an experiment that started the company: he sent the same cards to different grading companies, cracked them out and resubmitted them, and found that many came back with different grades. He says that led to a roughly ten-year effort to build a grading technology aimed at accuracy and consistency, and that TAG was awarded four patents with 134 approved claims. Those are TAG's own statements, but they explain the company's pitch: data and transparency first.
TAG accepts licensed standard-size trading cards made from 1989 to the present, up to 50pt thick, across Pokémon, Magic, One Piece, Topps, Panini, Upper Deck and many more. Its submission page noted in October 2026 that some card types were not accepted for now, including Yu-Gi-Oh!, pre-1989 cards, memorabilia cards and anything thicker than 50pt. Check its eligibility list before you send anything.
How TAG grading works
TAG describes its system as machine-learning image capture software, and says it prefers the term "machine learning" over "AI." Cards are imaged with what TAG calls photometric stereoscopic imaging, which maps surface defects. The software flags defects, then, according to TAG, all identified defects are reviewed by human grading experts before the grade is finalized. TAG calls that step Verification and says it is the longest stage of its process, used to catch false positives and keep results consistent.
The DIG report
Every TAG graded card comes with a DIG (Digital Image & Grading) report. You reach it by scanning the QR code on the slab label or by looking up the certification number. Highlights include:
- DINGS (Defects Identified of Notable Grade Significance): the specific defects that kept the card from a higher grade, mapped by location. TAG notes a defect that wouldn't change the grade isn't listed as a DING.
- Card Vision: a slider that blends the color image with TAG's surface-defect view, plus zoom up to 800x.
- Attribute breakdown for corners, edges, centering, surface and dimensions, with centering measurements.
- Pop, rank and chronology: how many copies TAG has graded, where yours ranks (rank needs the 1000-point score) and the order in which copies were graded.
This is TAG's biggest differentiator. Instead of a number on a label, you get the reasons. It is also why TAG says it generally won't accept grade disputes: the report is meant to show you exactly why a card got its grade, though TAG acknowledges no grading system is perfect.
The TAG grading scale
TAG scores cards from 100 to 1000 and maps that score to a familiar 1 to 10 grade. Half grades exist at every level except between 9 and 10: there is no 9.5. TAG's reasoning is that a card that beats its Mint standard is Gem Mint, and a card that beats Gem Mint is Pristine.
| TAG grade | Condition | TAG Score |
|---|---|---|
| 10 | Pristine | 990 to 1000 |
| 10 | Gem Mint | 950 to 989 |
| 9 | Mint | 900 to 949 |
| 8.5 | NM MT+ | 850 to 899 |
| 8 | NM MT | 800 to 849 |
| 7.5 | NM+ | 750 to 799 |
| 7 | NM | 700 to 749 |
| 6 to 1 | EX MT down to Poor | 650 to 699 down to 100 to 149 |
From TAG's published grading scale, checked October 2026.
Pristine vs Gem Mint
Both are 10s, but TAG says Pristine exceeds the industry standard for Gem Mint and represents less than 1% of the cards it has graded. Centering is where the gap shows most clearly in TAG's rubric:
| Grade | Front centering | Back centering (sports) | Back centering (TCG) |
|---|---|---|---|
| Pristine 10 | ~51/49 | ~54.5/45.5 | ~52/48 |
| Gem Mint 10 | ~55/45 | ~70/30 | ~65/35 |
| Mint 9 | ~60/40 | ~90/10 | ~75/25 |
Pristine also requires a virtually flawless surface, corners and edges, with TAG's rubric allowing only what it calls Non-Human Observable Defects on a Pristine surface. Any card that reaches Pristine gets the 1000-point score even if its service tier didn't include it. If you want to see where your card lands, measure it with the card centering calculator and read our card centering guide; TAG notes that a bordered card generally can't reach Gem Mint with any single centering measurement outside 55/45.
TAG grading cost and turnaround (October 2026)
TAG charges a flat fee per card with no upcharge based on card value, and says it doesn't require a declared value. Here is what its pricing page and service pages showed on October 7, 2026:
| Tier | Price per card | Est. turnaround | Max coverage per card | Status |
|---|---|---|---|---|
| Basic | $39.95 (Basic, sports/entertainment service page) | 75+ business days (pricing page) | $300 (pricing page) | At capacity on the pricing page |
| Standard (adds TAG Score) | $59.95 (Standard, TCG/CCG service page) | 45 business days (pricing page) | $500 | At capacity on the pricing page |
| Express | Not listed | 25 business days | $1,500 | At capacity on the pricing page |
| Priority | $149 | 5 business days | $2,500 | Limited slots |
| Walkthrough (DIG+ report) | $299 | 2 to 3 business days | $5,000 | Limited slots |
When we rechecked on October 18, 2026, TAG's pages listed Standard at $59.95 per card with $1,000 coverage and a 45 business day estimate, and showed no price for Basic or Base. Our cheapest way to grade cards guide has the current comparison.
Two caveats from the October 7 check. First, TAG's individual service pages and its pricing table didn't fully agree when we checked: the Basic and Standard service pages listed 30 estimated business days (and $1,000 coverage on Basic), while the pricing table showed the longer estimates above. Confirm the price, turnaround and coverage at checkout. Second, TAG says turnaround times are estimates, measured in business days from when its receiving team processes your package, and not guaranteed. Return shipping is calculated at checkout, and TAG offers an optional $49.95 Submission Kit in the US with supplies and prepaid shipping. Value and bulk services were paused.

The 2026 backlog, and what it tells you
The fairest knock on TAG in 2026 is turnaround. TAG's own backlog tracker says it paused Basic and Standard submissions on May 1, 2026 and Express on May 28 after unprecedented submission growth, and that at its peak the backlog was about 420% of its monthly processing capacity. It reopened submissions in limited "drops" starting August 27. By its September 30, 2026 update, TAG said the backlog was down about 96% from peak, recent orders were on schedule, expanded tiers were reopening, and it estimated full catch-up in October.
Two things are true at once. Long, unexpected waits are a real cost, especially with valuable cards in transit. And TAG publishing a public tracker with dated numbers is unusually open. If you submit, pick a tier with a turnaround you can live with and check the tracker first.
TAG vs PSA
- Transparency: TAG's DIG report explains every grade with images and mapped defects. That level of detail is the core of its pitch.
- Precision: TAG's 1000-point score separates a "high 10" from a "low 10" and ranks cards on a leaderboard. PSA grades on a 1 to 10 scale.
- Scale differences: TAG has Pristine above Gem Mint and no 9.5. Compare TAG's centering bands above with PSA's in our centering guide, and see PSA 10 vs PSA 9 for why one point matters so much.
- Pricing model: TAG charges flat fees with no value upcharge and doesn't require a declared value. Compare that with PSA's current tiers in our PSA cost guide.
- Resale: this is the big one, and it depends on your card. We haven't found a neutral source that publishes a reliable TAG to PSA price gap, so check recent sold listings for your exact card in both slabs at the same grade before you choose. If TAG copies are rare in sold data, that itself tells you the buyer pool is thinner for that card.

Pros and cons
| Pros | Cons |
|---|---|
| Detailed DIG report with images, mapped defects and centering measurements | Regular tiers were at capacity in October 2026 after a long backlog |
| 1000-point score and leaderboard rank on Standard and up | Resale premium vs PSA varies by card; check sold listings |
| Flat pricing with no value upcharge | No 9.5 grade, and Pristine is very hard to reach |
| Paperless inscribed label, UV-resistant slab and Proof anti-counterfeit tech | Not accepting pre-1989 cards or Yu-Gi-Oh! at the time of writing |
| Public backlog tracker and published rubric | Disputes generally not accepted; the report is meant to explain the grade |
Who TAG is good for
- Collectors who want to see why. If a bare number frustrates you, the DIG report is the reason to choose TAG.
- Personal collection keepers, where display, data and consistency matter more than maximizing resale today.
- Modern TCG and sports cards within TAG's eligibility rules, especially strong cards where a high score or Pristine designation means something to you.
- Less ideal for quick flips of cards where buyers clearly pay more for a specific other slab. Check the sold data first.
How to verify a TAG slab
- Scan the QR codeEvery TAG label has a QR code that opens the card's DIG report. Compare the images in the report with the card in the slab, including any small marks.
- Look up the cert numberUse TAG's cert search, or the link format tagd.co/ followed by the cert number, instead of trusting a link a seller sends you.
- Check the Proof codeTAG says every slab has Proof anti-counterfeit technology you can scan with your phone to verify the slab is authentic.
- Inspect the labelTAG inscribes the grade and data directly into the clear acrylic case rather than using a paper insert. A paper flip inside a "TAG" slab is a red flag.
Pre-grade on the TAG scale before you pay
Whether you choose TAG or PSA, the most expensive mistake is paying to grade a card that comes back lower than you expected. Binder AI can estimate a grade on the TAG scale, or PSA or BGS, from photos of the front and back, with subgrades for centering, corners, edges and surface and written condition notes. It's an estimate, not an official TAG grade, and Binder AI isn't affiliated with TAG, PSA or Beckett. It's a fast way to spot the off-center card or the whitened back edge before you send it. Our card grading criteria guide explains what each subgrade looks at.
