What Is Card Grading and Why Does It Matter?
Card grading is the process of having a professional, third-party company evaluate your trading card for authenticity, quality, and condition. The goal is to provide a trusted, objective assessment that determines both market value and collector credibility. Once graded, your card is encapsulated in a sealed, tamper-proof case — often called a slab — that guarantees its certified state for years to come.
How the Grading Process Works
When you send a card to a grading company, it goes through several meticulous steps:
- Authentication – confirming the card is genuine.
- Condition Evaluation – inspecting the four key elements:
-
- Corners: Are they sharp and clean?
- Edges: Are there chips, frays or whitening?
- Centering: Is the image perfectly aligned within the borders?
- Surface: Are there scratches, print lines, or stains?
- Scoring – each factor receives a numeric grade that contributes to an overall score on a 1–10 scale (10 = Gem Mint).
- Encapsulation – the card is sealed in a protective case with a label that lists its grade, company, and serial number for verification.
Why It Adds Value
A graded card isn’t just protected — it’s certified, standardized, and elevated. The grading label acts as a seal of authenticity and condition, instantly communicating trust to buyers and collectors alike. This transparency is what drives the market: everyone speaks the same language when they see a PSA 10, BGS 9.5, or SGC 9.
But grading does more than validate — it actually creates scarcity within scarcity.
Even if 500 copies of a card exist, not all are equal. A Gem Mint 10 version might represent only a small percentage of all those produced. Lower grades (8s or 9s) are still desirable, but the population gap — the number of cards that achieved each grade — determines real-world rarity. A “pop 12” PSA 10 instantly becomes a grail-level piece compared to hundreds of lower-grade copies.
This standardized grading system also brings true comparability to the market. Collectors can accurately evaluate two identical cards from different sellers without relying on subjective descriptions like “near mint” or “good condition.”
That consistency fuels confidence — and confidence fuels prices.
Key Grading Terms Every Collector Should Know:
Gem Mint (10)
“Gem Mint” is the highest possible grade a trading card can achieve — typically a 10/10 on the grading scale. A Gem Mint card shows virtually no flaws. This condition is the benchmark for perfection — the kind of card that collectors dream of pulling and investors seek for long-term appreciation. Because so few cards ever achieve this standard, Gem Mint grades command a significant premium on the market. There are different names/terms for the grades and conditions.
Overview:
| Grade | Name / Term | Condition / Meaning |
|---|---|---|
| 10 | Gem Mint | Perfect card: flawless in every way, perfectly centered, sharp corners, pristine surface. |
| 9.5 | Mint+ / Pristine (BGS) | Almost perfect, only the tiniest imperfections visible under close inspection. |
| 9 | Mint | Very high quality; nearly flawless, just shy of Gem Mint. |
| 8.5 | Near Mint+ | Minor, almost unnoticeable flaws; minimal edge or corner wear. |
| 8 | Near Mint | Small imperfections like slight corner wear or minor print defects; still very good. |
| 7 | Near Mint-Mint | Visible wear on edges or corners; slight creases possible; still collectible. |
| 6 | Excellent-Mint | Noticeable wear; small bends, scratches, or minor creases. |
| 5 | Excellent | Clearly visible flaws; not perfect but acceptable for collectors without premium expectations. |
| 4 | Very Good-Excellent | Multiple noticeable issues; bends, edge wear, or surface imperfections. |
| 3 | Very Good | Heavy wear, scratches, bends; still identifiable but lower market value. |
| 2 | Good | Significant damage; heavily worn edges, corners, and surface. |
| 1 | Poor | Severely damaged; generally not considered collectible, mainly for nostalgia. |
Pop / Population
“Pop” stands for population — the number of copies of a specific card that have received a particular grade from a grading company (e.g., PSA or BGS).
For example: If a PSA report shows “Pop 12” for a specific card in grade 10, it means only 12 Gem Mint copies exist worldwide in PSA’s database.
Population reports are crucial for understanding true rarity within a print run. Even if a card was produced in 500 copies, maybe only a handful achieved a perfect Gem Mint grade — and those become the elite tier within the collector market.

Should Every Card Be Graded?
Not necessarily. Grading costs can range from 20€ to over 300€ depending on service level and declared value. It’s best reserved for:
- Rookie cards or key players
- Limited or numbered editions
- Autographs and memorabilia pieces
- Cards with potential long-term appreciation
Before submission, inspect your cards under good lighting and consider a pre-grading service to avoid unnecessary fees.
A Seal of Legacy
Beyond value, grading gives permanence. It locks in your card’s story, preserving its state for generations — a true collector’s mark of excellence.
