PSA vs BGS vs CGC vs SGC — What the Grader Names Actually Mean
On any vault-backed platform — Courtyard, Phygitals, Collector Crypt — every card arrives already inside a grading company’s slab. The platform is trusting that slab, which means you are trusting it. Here’s what the four names on the labels actually are.
Grading is a two-part product: authentication (is the card real?) and condition grading (a score, typically 1–10). The slab — a sealed, labelled, cert-numbered case — is the physical output. The cert number is the part you verify.
The four majors (2025 volumes per GemRate, via Yahoo Sports)
| Grader | Cards graded 2025 | Known for |
|---|---|---|
| PSA (Professional Sports Authenticator) | ~19.3 million | Largest by far; strongest resale recognition; single overall grade (no subgrades) |
| CGC | ~6–7 million | Built its reputation in TCG (Pokémon, Magic); expanded into sports |
| SGC | ~3–4 million | Long-established; strong vintage-card reputation; fast turnaround |
| BGS (Beckett) | ~2–3 million | Subgrades — four separate scores (centering, corners, edges, surface) on the label; the “black label” 10 is its premium product |
Major authenticators graded 26.6 million cards combined in 2025 — the most GemRate has recorded in a single year, driven largely by Pokémon/TCG submissions (16.8M TCG/non-sport vs 10M sports). Grading volume is demand-side evidence for the whole card market — including the vault-backed platforms that only accept graded stock.
What actually differs for a collector
- Scale and recognition: PSA slabs carry the broadest resale recognition; that’s why vault platforms treat PSA as the default reference.
- Subgrades: BGS shows four component scores; PSA gives one number. If you care why a card got its grade, subgrades tell you.
- Category strength: CGC’s depth is TCG; SGC’s is vintage. The “right” grader depends on the card.
- Population reports: each grader publishes population data (how many of a card exist at each grade). Check the pop report before treating a grade as scarce.
The one habit that matters
Whatever the label says: verify the cert number on the grader’s own website. Every major grader runs a free online cert lookup. If a slab’s cert number doesn’t resolve — or resolves to a different card — that’s the entire answer about that item. On tokenised platforms, do this check on the listing’s stated cert before you buy; the token inherits whatever truth is in the slab.
What grading doesn’t do
A slab certifies the card inside it — it says nothing about the platform custodying it, the token representing it, or whether redemption will be honoured. Grading is one link in the chain. The full checklist — vault, custody, redemption, platform status — is in the provenance & authenticity explainer.
Bottom line: the grader names are different products — PSA for scale and recognition, BGS for subgrades, CGC for TCG depth, SGC for vintage — but every one of them only authenticates the card. Verify the cert on the grader’s own site, then verify everything else separately.
