PSA, CGC, or TAG: grading Pokémon cards in 2026

Grading does three things for a card: it authenticates it, it assigns a condition grade on a public scale, and it seals the card in a tamper-evident holder with a certification number that anyone can look up. For a grail-level card, those three services change what the card is — a raw card is an argument about condition, a slabbed card is a record. As of 2026, Pokémon collectors mainly weigh three graders: PSA, CGC Cards, and TAG. They share the familiar 1–10 scale but differ in meaningful ways above and below it.

PSA

PSA, founded in 1991 and the oldest of the three, grades on a ten-point scale whose named grades run from Gem Mint 10 — "virtually perfect," in PSA's language — down through Mint 9, NM-MT 8, NM 7, EX-MT 6, EX 5, VG-EX 4, VG 3, and Good 2 to Poor 1. Grading only happens after a card has been deemed authentic. PSA's published standards are explicit that grading is not purely mechanical: graders weigh eye appeal, and the company "reserves the right, based on the strength or weakness of the eye appeal, to make a judgment call on the grade." A card with an otherwise strong grade can carry a qualifier on its label — MK, for example, marks cards with writing or ink marks — and cards that cannot be graded at all are returned with no-grade designations such as Evidence of Trimming, Questionable Authenticity, or Miscut. Graded cards are sealed in a sonically sealed, tamper-evident case behind the LightHouse label, which displays the grade and certification number, and every cert can be checked against PSA's public verification database.

CGC Cards

CGC, founded in 2000 and long established in comics, grades trading cards through its CGC Cards division. Its card scale is the most granular of the three on paper: half-point grades run through the whole ladder — Mint+ 9.5, NM/Mint+ 8.5, Near Mint+ 7.5, and so on — with descriptive standards for each step, down to Poor 1. At the top, CGC splits the perfect grade in two: Gem Mint 10, and above it Pristine 10, reserved for a card that is "virtually flawless to the naked eye" with perfect centering under magnification, and identified by a special Pristine 10 label. The CGC holder is ultrasonically welded and built to resist tampering, and its label carries several security features — microprinting, UV ink, holographic foil, and a unique certification number with barcode. A QR code on the back of the label links to the card's entry on CGC's website, including high-resolution images captured during encapsulation, and every cert can be checked through CGC's cert lookup tool. CGC also publishes a population report covering everything it has graded.

TAG

TAG, established in 2015, is the technological outlier: cards are scored by a patented photometric stereoscopic imaging system rather than by eye alone. Each card receives a 1000-point TAG Score that maps onto the standard 1–10 scale — 10 Pristine covers 990–1000, 10 Gem Mint 950–989, 9 Mint 900–949, 8.5 NM MT+ 850–899, and so on down the ladder, with half points on every grade level except between 9 and 10. TAG states that a Pristine grade exceeds the industry standard for a Gem Mint 10 and represents less than one percent of the cards it has graded. Every TAG card comes with a Digital Imaging & Grading (DIG) report, reached by scanning the QR code on the slab, which shows high-resolution images of detected defects, per-attribute scoring, and the defects TAG calls DINGS — Defects Identified of Notable Grade Significance. The slab itself is distinctive: the grade and data are inscribed directly into the clear acrylic with no paper insert, and each slab carries a PROOF security mark that can be verified with TAG's free smartphone app.

How the scales actually differ

All three ladders end in a 10, but the 10s are not the same shape. PSA has a single top grade, Gem Mint 10. CGC and TAG each stack a second, stricter tier — Pristine 10 — above Gem Mint. And where PSA expresses nuance through qualifiers and grader judgment, CGC expresses it through half-point granularity, and TAG through the published 1000-point score behind each grade. None of these systems converts cleanly into another: a grade is a claim within one company's standard, not a universal measurement. When comparing slabs across services, compare the standards, not just the number on the label.

Cert verification and population reports

Every service above gives each slab a certification number and a public lookup: PSA's cert verification database, CGC's cert lookup (plus the QR code to its own photos of the card), and TAG's cert search and DIG reports, with certs formatted as one letter followed by seven numbers. Checking the cert before buying any slab should be reflexive — though note PSA's own caution that verification "does not eliminate risk," since counterfeit labels have been made using real cert numbers. Our guide to spotting fake slabs covers that in detail. Each service also maintains a population report — a census of how many copies it has graded of each card at each grade — which is where scarcity questions get answered; we cover those in how to read pop reports.

Choosing, as of 2026

There is no universally correct answer. PSA offers the longest track record and the hobby's most established label; CGC offers a finely divided scale, a two-tier top end, and photographic records of every card it encapsulates; TAG offers machine-measured consistency and the most transparent data trail behind each grade. For a grail card, the honest advice is to decide what you want the slab to say about the card — a market-standard grade, maximal condition granularity, or a published measurement — and submit accordingly.
