Card grading is the process of having a professional third-party company evaluate a card's condition and seal it in a tamper-proof plastic case with an official grade. It's become an essential part of the modern card market.
Why Grade Cards?
Graded cards:
- Sell for significantly more than 'raw' (ungraded) copies
- Are authenticated — fakes are identified
- Are protected permanently in a hard case
- Are easier to buy and sell because condition is objective
The Big Three Grading Companies
PSA (Professional Sports Authenticator)
The most recognized name in card grading. PSA grades are the most trusted for vintage cards and command the highest premiums. A PSA 10 (Gem Mint) on a popular rookie can be worth 5–10x a PSA 8.
PSA Scale:
- PSA 10 — Gem Mint
- PSA 9 — Mint
- PSA 8 — Near Mint-Mint
- PSA 7 — Near Mint
- PSA 6 and below — Declining condition
BGS (Beckett Grading Services)
Beckett uses a subgrades system, giving separate scores for centering, corners, edges, and surface. This detail appeals to collectors who want to know exactly what's good (or not) about a card. BGS 9.5 (Gem Mint) with a 10 subgrade is called a 'Black Label' and is highly prized.
SGC (Sportscard Guaranty)
SGC is known for fast turnaround times and is popular for vintage cards. It's gaining popularity with modern collectors too, especially at lower price points.
Is Grading Worth It?
Grading makes sense when:
- The card is worth $50+ raw
- The card appears to be in very high grade (near-perfect condition)
- You intend to sell and want maximum value
- You want authentication for a valuable vintage card
For common cards worth under $20, the grading fee (typically $20–$100+ depending on service level) doesn't make economic sense.
How Cards Are Graded
Graders examine four areas: 1. Centering: Is the image centred between the borders? 2. Corners: Are all four corners sharp or worn? 3. Edges: Are the edges of the card clean? 4. Surface: Are there scratches, print defects, or staining?
Even one small flaw can drop a card from a 10 to a 9 — and that can mean hundreds of dollars difference in value.
