Sports Card Grading: PSA, BGS, SGC

About this quiz

What you’ll practice

From centering to surface flaws, this quiz helps you spot what graders look for and how grading scales differ between PSA, BGS, and SGC.

Each question uses 4 options and there’s no timer, so you can slow down and think through edge cases like qualifiers, subgrades, and label wording.

Difficulty and question settings

Difficulty is balanced with a mixed pool: some questions focus on straightforward definitions, while others ask you to compare standards or apply them to scenarios.

Choose your question count and difficulty before you start—go shorter for quick review, or longer to build consistency across all three grading companies.

Common pitfalls to avoid

Mixing up PSA grades with BGS subgrades and “Pristine/Black Label” terminology
Overvaluing centering while ignoring surface print lines, scratches, or dimples
Confusing SGC label/holder eras and what they imply (without guaranteeing a grade)
Assuming every flaw affects all card types the same (chrome vs paper stock)
Forgetting that eye appeal can swing borderline grades even with similar defects
