Edges and surface quality can make or break your card grade. Learn what graders look for and how to evaluate these often-overlooked sub-scores.
In short: Edges and surface together account for 60% of a BGS grade and are heavily weighted by PSA and CGC too. Both are easy to overlook but impossible for graders to miss. Pre-screen with CardGrade.io to catch edge chips and surface scratches before you pay grading fees.
When collectors think about card grading, centering and corners tend to dominate the conversation. But edge quality and surface condition are equally weighted by every major grading company and are often the reason cards fall short of top grades. A card with perfect centering and sharp corners will still receive a mediocre grade if the edges are chipped or the surface is scratched. This guide covers everything you need to know about evaluating card edges and surfaces before submitting to PSA, BGS, or CGC. Understanding these two sub-grades will help you make smarter submission decisions and avoid costly surprises.
Edge evaluation covers the entire perimeter of the card, all four sides, on both the front and back. Graders use magnification and specific lighting angles to identify defects that are invisible to casual inspection.
Chipping: Small fragments of the card's outer layer breaking away from the edge. This is the most common edge defect and appears as tiny white spots or rough patches along the border. Chipping is especially visible on cards with dark borders or foil edges. Whitening: The card stock is composed of multiple layers. When the outer layer wears away or separates slightly, the white inner core becomes visible along the edge. This is different from chipping because the surface remains relatively smooth but the color is compromised. Peeling or delamination: In more severe cases, the card layers begin to separate along the edge. This is most common in thicker cards, multi-layered inserts, and cards that have been exposed to moisture. Rough cutting: Manufacturing imperfections where the cutting die was not perfectly sharp or aligned. This results in a jagged or uneven edge rather than a clean, straight cut. While this is a factory defect, graders still penalize it. Dings and dents: Physical impacts that create small indentations along the edge. These can result from cards hitting each other during shuffling, being stored in tight stacks, or being handled without care. Roller marks: Faint lines running parallel to one edge, caused by the manufacturing rollers. These are subtle but visible under magnification and can affect edge sub-grades.
| Defect Level | PSA Grade Impact | BGS Edge Sub-Grade | CGC Edge Sub-Grade |
|---|---|---|---|
| No visible defects at 10x | 10 eligible | 10 | 10 |
| Minor roughness, barely visible at 10x | 9-10 range | 9.5 | 9.5 |
| Small chip or slight whitening | 8-9 range | 8.5-9.0 | 8.5-9.0 |
| Multiple chips or moderate whitening | 7-8 range | 7.5-8.0 | 7.5-8.0 |
| Significant chipping, peeling, or damage | 6 or below | 7.0 or below | 7.0 or below |
Follow this systematic process:
Sports cards (Topps, Panini): Factory cutting quality varies significantly between print runs. Check for rough cutting and uneven edges, especially on cards from higher-volume print runs. Pokemon TCG: Modern Pokemon cards tend to have consistent cutting but are prone to whitening on the edges due to the card stock used. Holographic and full-art cards can show edge peeling where the foil layer meets the cardboard. Vintage cards (pre-1990): Expect some degree of edge wear. The card stock used in older productions was softer and more susceptible to chipping. For vintage, graders use era-appropriate standards, but edges still matter. Thick insert cards and patches: Multi-layered cards are more susceptible to delamination along the edges. Inspect the edge profile to ensure all layers are intact and aligned.
Surface evaluation is considered the most challenging aspect of card grading because many surface defects are only visible under very specific conditions. A card can look perfect in your hand and reveal scratches, print lines, or other issues under the grader's lamp.
Scratches: The most common surface defect. Scratches range from hairline marks only visible at specific angles to deep grooves visible to the naked eye. They can occur from handling, stacking, sliding in and out of sleeves, or contact with other cards. Print lines: Fine lines that appear in the ink layer during the printing process. These are manufacturing defects, not handling damage, but graders penalize them nonetheless. Print lines are especially common on holographic and foil cards. Print dots: Small ink spots or missing ink spots that result from printing imperfections. Like print lines, these are factory issues that affect the surface grade. Staining or discoloration: Caused by contact with moisture, oils from fingers, food, or chemical exposure. Stains can range from barely visible spots to obvious discoloration. Older cards may develop age-related toning. Indentations: Depressions in the card surface caused by writing pressure from nearby surfaces, rubber bands, heavy stacking, or point impacts. Indentations are often invisible from the front but reveal themselves when the card is tilted under light. Wax staining: Common on vintage cards that came in wax packs. Wax residue can penetrate the card surface, creating translucent spots. This is especially problematic for cards from the 1970s-1990s era. Fogging or clouding: A hazy appearance on the surface, typically caused by moisture exposure or chemical contact. This is most noticeable on glossy or foil surfaces. Refraction issues (holo cards): On holographic cards, surface defects can disrupt the holographic pattern, creating dead spots or irregular refraction. These are particularly penalized because they affect the visual appeal of premium card types.
| Condition | PSA Grade Impact | BGS Surface Sub-Grade | CGC Surface Sub-Grade |
|---|---|---|---|
| Flawless under magnification | 10 eligible | 10 | 10 |
| Minor print lines or barely visible marks | 9-10 range | 9.0-9.5 | 9.0-9.5 |
| Light scratches visible at angle | 8-9 range | 8.0-9.0 | 8.0-9.0 |
| Moderate scratches or staining | 7-8 range | 7.0-8.0 | 7.0-8.0 |
| Heavy surface damage | 6 or below | Below 7.0 | Below 7.0 |
Surface inspection requires more technique than any other sub-grade:
Foil and holographic cards: These surfaces are magnets for fingerprints and micro-scratches. Handle only by edges and always wear clean, lint-free gloves when evaluating. Matte finish cards: More resistant to visible scratching but show staining and print defects more clearly. The textured surface can also trap dirt and oils. Vintage cards: Surface assessment must account for era-appropriate conditions. A 1952 Topps card is not held to 2024 printing standards, but surface damage from handling over decades still affects the grade. Autographed cards: The signature itself is not graded as part of the surface (it receives a separate auto grade), but damage caused during the signing process, such as indentations or ink bleed, affects the surface grade.
Your final grade is influenced by all four sub-grades together. Understanding how they interact helps you predict grades more accurately:
BGS uses a weighted formula to calculate the overall grade from sub-grades:
| Sub-Grade | Weight |
|---|---|
| Centering | 20% |
| Corners | 20% |
| Edges | 30% |
| Surface | 30% |
| Edges and surface together account for 60% of the BGS grade. A card with a 10 in centering and corners but 8.5s in edges and surface will receive a BGS 9.0 at best, not a 9.5. This weighting makes edge and surface evaluation critical for BGS submissions. |
PSA does not publish explicit sub-grade weights, but experienced submitters know that surface and edge issues are heavily penalized. PSA graders evaluate the overall impression, and a noticeable surface scratch or edge chip tends to cap the grade at 8 or 9 regardless of how good the centering and corners are.
CGC provides optional sub-grades (for an additional fee) and uses standards similar to BGS. Their grading is generally considered strict on surface quality, particularly for modern cards where manufacturing quality is expected to be high.

Even after you evaluate your card, damage can occur between inspection and the grader's desk if you are not careful:
