3. Compare to Professionally Graded Cards

If you have professionally graded cards, use them as a reference for centering. Place the raw card next to a PSA or BGS graded card and compare the border thickness.

Tip:

For a more accurate assessment, photograph both cards side by side to easily identify misalignments.

4. Check for Printing Errors

In some cases, misaligned printing can make centering appear off. Learn how to identify card printing errors to avoid misjudging centering.

Bonus Tips or Mistakes to Avoid

Avoid Handling the Card Directly: Use gloves to prevent fingerprints and smudges.
Use a Magnifying Glass: Helps to see finer details, especially for older or vintage cards.
Compare with Grading Standards: Familiarize yourself with PSA, BGS, and CGC centering guidelines.
Store Cards Properly: After checking centering, place the card in a protective sleeve to prevent damage.
Consider AI Grading for Consistency: AI tools provide objective assessments, reducing human error.
