What is card grading?
Grading is the process of having a trading card professionally assessed for condition and authenticity, then sealed (“slabbed”) in a tamper-evident case with a numbered grade. A graded card is protected, verified as genuine, and its condition is certified by an independent third party — which is why graded cards often command higher, more stable prices than raw cards.
The main grading companies
PSA
Professional Sports Authenticator. The most widely recognised grader globally, especially for Pokémon. Grades 1–10.
BGS
Beckett Grading Services. Known for detailed subgrades (centering, corners, edges, surface) and the coveted Black Label 10.
CGC
Certified Guaranty Company. Fast-growing in TCG, strong reputation, often more accessible turnaround and pricing.
How the 1–10 scale works
Cards are graded on a scale from 1 (Poor) to 10 (Gem Mint). The grade reflects centering, corners, edges, and surface. A few reference points:
- 10 — Gem Mint: virtually flawless. Commands the highest premium.
- 9 — Mint: excellent with only the most minor imperfections.
- 8 — Near Mint–Mint: very clean, slight wear under close inspection.
- 7 and below: increasingly visible wear — still collectible, priced accordingly.
Even a single grade can dramatically change a card’s value — a PSA 10 can be worth many times a PSA 9 of the same card. That’s why grading, and trusting the grade, matters.
Should you grade a card?
Grading makes most sense when: the card is valuable or rare, it’s in excellent condition (grading a damaged card rarely pays off), and you plan to sell, insure, or protect it long-term. For lower-value cards, the grading fee can outweigh the benefit. If you’re unsure, ask us — we’ll give you an honest view before you spend.
