Grading

Card grading explained: PSA, BGS and CGC

What card grading means, how the 1–10 scale works, what PSA 10 and gem mint mean, and when it's worth grading a card.

What card grading is

Grading is the process of sending a card to a third-party company that authenticates it (confirms it's genuine), evaluates its condition against a consistent standard, assigns a numeric grade, and encapsulates it in a sealed plastic slab with a unique certification number. The slab protects the card and lets buyers trust its condition without handling it.

How the 1–10 scale works

Most graders use a 1–10 scale based on centering, corners, edges and surface. Higher is better:

GradeMeaning
10 — Gem MintVirtually flawless; sharp corners, clean edges, near-perfect centering.
9 — MintExcellent with one very minor flaw.
7–8 — Near MintLight wear; a strong collector grade.
4–6 — Excellent to VGNoticeable wear but presentable.
1–3 — Poor to GoodHeavy wear, creasing or damage.

Companies differ in detail: BGS issues sub-grades and a half-point 9.5 ('Gem Mint'), and a BGS 10 ('Black Label') is extremely rare. PSA is the most widely traded and often the most liquid for resale.

When is it worth grading a card?

Grading costs a fee per card and takes time, so it only makes sense when the graded value comfortably exceeds the raw value plus fees. Rough guidance:

  • Grade cards that look near-mint or better and have real raw value — the upside is largest at PSA 9–10.
  • Don't grade heavily played common cards; the fee will exceed any gain.
  • Consider the grade odds honestly: small surface or centering flaws can cap a card at a 8 or 9.
  • Check current raw vs graded prices before submitting — Riply's graded comparisons make this quick.

Frequently asked questions

What does PSA 10 mean?

PSA 10 is 'Gem Mint' — a near-perfect card with sharp corners, clean edges, good centering and a clean surface. It's the top PSA grade and usually the most valuable.

Which grading company is best?

PSA is the most widely traded and typically the most liquid for resale; BGS is known for sub-grades and its rare Black Label 10; CGC is a strong, often faster alternative. The 'best' depends on the card, cost and turnaround.

How do I know if grading is worth it?

Compare the card's graded price to its raw price plus grading fees. If a likely PSA 9 or 10 is worth well above the raw price and fee, it's worth considering. Riply shows raw and graded values side by side.
