Learn what to look for before you submit.
Use this guide to inspect a raw card, describe what you see, and make a more informed grading decision before paying submission fees.
Getting Started with Card Grading
Card grading is a professional review of a card's condition and authenticity. The grading company assigns a grade and seals the card in a protective holder, often called a slab.
Why collectors grade
A grade can protect a card, make its condition easier to understand, and sometimes increase buyer confidence or resale value.
Why pre-grading matters
Submission, shipping, and insurance fees add up. A careful inspection helps you avoid paying to grade cards with obvious condition problems.
The Four Main Areas Graders Look At
Inspect all four areas on both the front and back. One strong-looking area does not cancel out a major defect somewhere else.
Centering
How evenly the printed design sits inside the card's borders from left to right and top to bottom.
Corners
The sharpness and condition of all four corners, including whitening, bends, softness, and dings.
Edges
The condition of the card's sides, including whitening, chips, rough cuts, fraying, and silvering.
Surface
The front and back faces of the card, checked for scratches, print defects, dents, stains, creases, and impressions.
Centering Guide
Centering compares the border space around the printed image. Check the front and back separately because one side may be noticeably worse.
Left / right ratio
A 50/50 result is perfectly even. A 55/45 result means one side is slightly wider. Larger differences increase grade risk.
Top / bottom ratio
Compare the top border with the bottom border in the same way. Some cards are off-center in both directions.
Front centering
The front is often the first thing buyers notice, so visible front misalignment can be especially important.
Back centering
Do not skip the back. A centered front can still have a clearly off-center back.
Estimate the left/right and top/bottom balance for the front, then repeat for the back.
In the calculator, choose or enter the closest centering values for each direction and side.
If one direction is clearly more off-center, expect it to create more grade risk.
Corner Guide
View every corner from the front and back. Small corner flaws can hide against light borders, so use close inspection and angled light.
Corner whitening
White fibers or color loss at the tip or along the corner. More visible whitening usually means more grade risk.
Soft corners
A corner that looks rounded or worn instead of crisp and sharp.
Bent corners
A corner that is folded, lifted, or no longer flat. This is more serious than minor softness.
Corner dings
A compressed or struck area that changes the corner's shape, sometimes with a small indentation.
Edge Guide
Slowly rotate the card and inspect each edge from multiple angles. Check both faces because wear may show more clearly on one side.
Whitening
Small areas where the printed color has worn away and the lighter card stock shows through.
Chipping
Missing flakes of ink or surface material, often seen along dark or foil borders.
Rough cuts and fraying
An uneven factory cut or loose fibers along the edge. Record how much of the edge is affected.
Silvering
A bright metallic-looking line where foil or card layers show at the edge.
Surface Guide
Surface issues can disappear in flat lighting. Tilt the card slowly under a bright light and inspect the front, back, artwork, borders, and holo area.
Scratches and holo scratches
Lines cut or rubbed into the surface. Holofoil can reveal fine scratches only when the light moves.
Print lines and roller marks
Factory-made lines or tracks left during printing. They may be straight, repeating, or visible only at an angle.
Dents, dimples, and impressions
Indented areas that change the card's surface. A dimple is usually small; a dent or impression may be deeper or wider.
Creases
A fold line that bends or breaks the card's structure. Even a short crease can create major grade risk.
Stains and fingerprints
Visible residue, discoloration, oil, or dirt. Avoid aggressive cleaning that could damage the card.
Check the whole surface
Look beyond the main artwork. Defects may sit in borders, text boxes, backs, or low-contrast areas.
Defect Severity Guide
Choose severity based on how easy the defect is to see and how much of the card it affects. Be consistent rather than optimistic.
Hard to see and usually needs angled light or close inspection.
Visible on closer review and likely worth recording in your decision.
Easy to notice and likely grade-impacting.
A major issue that usually makes grading a poor financial decision.
Visibility Guide
Visibility describes the viewing conditions needed to notice a defect. Use it together with severity for a clearer record.
Angled light only
The issue appears only while tilting the card through reflected light.
Close inspection
The issue is visible when looking carefully at the card from a short distance.
Normal light
The issue can be seen during an ordinary front or back review without special positioning.
Immediately obvious
The issue stands out quickly and is likely to affect both eye appeal and grade expectations.
When to Submit vs. Hold
Condition is only one part of the decision. Compare the likely grade, grading costs, card value, personal importance, and your tolerance for risk.
The inspection and value estimates support sending the card for grading.
The card needs better photos, another inspection, stronger comps, or more confidence before submitting.
The financial case is weak, but grading may still make sense for protection, display, or sentimental value.
Major defects, low upside, or high costs make grading a poor choice based on the information entered.

Advanced Calculator
Use it for defect-by-defect logging, risk-adjusted value decisions, multiple defects, photo references, and a saved report.
Photo / Inspection Setup Tips
Avoid deep shadows and strong glare that hide defects.
Review every corner, edge, border, and surface area on both sides.
Move the reflection across the surface to reveal scratches, dents, dimples, lines, and impressions.
Use a clean background that makes whitening and chipping easier to see.
In the Advanced Calculator, note which image shows each defect so you can find it again later.
Why upload card images?
Photos help document a card’s pre-submission condition. Front and back overview images are recommended, while defect closeups are useful for dents, scratches, whitening, and corner issues. Photos do not guarantee that a grading company will accept them as proof, but they give the collector a better record.
