If you look at a card straight on, it looks like a Ten. But the PSA grader will spend 10 seconds tilting it under a halogen light. That's when the nightmares appear.
The "Angle Check" Technique
You cannot grade surface straight on. You must reflect light across the surface.
- Hold the card flat in your hand (gloved).
- Position under a bright single-source lamp.
- Tilt to 45 Degrees. Watch the reflection of the bulb travel across the glossy surface.
- Scan the Reflection. If the reflection "jumps" or breaks, you found a dimple or scratch.
The "Big 3" Factory Defects
1. Print Lines
What: A horizontal or vertical line where the foil didn't bond.
Verdict: Instant PSA 9. If severe, PSA 8.
2. Dimples
What: A tiny indentation (crater) in the surface.
Verdict: One tiny dimple *might* gem. Two is a 9.
3. Spider Webbing
What: Fine hairline scratches that look like a web.
Verdict: Usually from wiping with a dirty cloth. PSA 8 territory.
Paper Cards: "Surface Wrinkles"
On vintage or paper cards (like 1986 Fleer), look for wrinkles. These are often invisible from the front but show up on the back.
Pro Tip: Always check the back of the card just as thoroughly as the front. A "paper wrinkle" on the back makes the card a PSA 5 instantly, even if the front looks perfect.
