What PSA looks for: corners, edges and surface

When a collector says a card looks mint, the description often means that the artwork looks clean from a normal viewing distance. A useful submission inspection asks more specific questions. Is the corner actually sharp? Does the edge have missing color? Is that bright streak a reflection or a scratch? Does the back show wear that the front hides? Write down what you can see before trying to attach a grade to it.

Organize the inspection around centering, corners, edges and surface. The categories help you work systematically, but they are not a recipe for averaging away damage. A beautiful front cannot make a crease disappear. Your goal is to document the strongest visible limitation and the areas you cannot inspect confidently, then compare the card with the grading company's published standard.

What the published standard establishes

PSA's Gem Mint 10 description calls for sharp corners, focus and original gloss, without staining, while allowing a slight printing imperfection when appearance is unaffected. Its standards also reserve judgment for eye appeal. That is a demanding description of the whole card, not a reward for a single attractive feature. The source is PSA's standards page, fetched October 22, 2026.

The text version available in that fetch exposed the Gem Mint definition and the additional terms, but not the other selectable grade definitions. We therefore do not present the lower-grade descriptions as freshly verified quotations here. Our related grading-standards guide records the full ladder with its earlier source date. For a current grade-by-grade comparison, open PSA's linked page and select the relevant grade yourself before submitting.

PSA's separate grading-tips articles explain why surface inspection matters. Its historical guidance generally places front wrinkles around EX 5 and reverse wrinkles around EX-MT 6, with severity affecting the outcome. Another example puts glue or tape staining around Good 2, subject to appearance. These are PSA's examples, not automatic grades assigned by this guide. Both original articles were read on October 22, 2026.

Corners: check the tip and the stock behind it

Start with a whole-card view, then inspect each corner on the front and back. Keep the card supported so that examining a corner does not bend it. Look for a rounded outline, a pale spot where color is missing, fibers standing away from the edge, or a compressed section of stock. Compare the corner with the others without assuming that symmetry proves it is undamaged.

For a useful photograph, focus on the corner itself and leave enough surrounding border to show where it belongs. A very tight crop of an unidentified white patch is hard to interpret later. Use a background that contrasts with the card's edge. Check the preview at full size: if the tabletop is sharp and the corner is soft, refocus and take the photo again.

Do not turn every ambiguous bright spot into a damage claim. Move the light and examine the area in person. If the spot disappears as the reflection changes, take another photograph that explains the difference. If it remains visible, document it honestly. Avoid using blur, portrait mode or a smoothing filter to make the close-up look cleaner than the card.

Edges: follow the entire perimeter

An edge inspection is different from a corner inspection. Follow each side from corner to corner and look for missing color, notches, rough stock and separation between layers. Check the reverse as well. Dark printing can make exposed pale stock easy to notice, while a pale border can make the same kind of damage harder to photograph. Use contrast and lighting rather than assuming one design is inherently better preserved.

Photograph a suspect edge with nearby artwork visible so you can relocate it. A low-angle view can help explain a raised or compressed section, but keep a straight-on reference too. Do not rest a ruler or another hard object on the surface to point at the flaw. Describe its location in your notes instead. If the edge is hidden by a holder, label that part of the inspection incomplete.

Avoid trying to tidy a rough edge before photographing it. The inspection should preserve the card as it is. PSA's additional terms warn about trimming, recoloring and other alterations. If the edge looks unusual for the issue, that is a reason to seek an informed opinion, not a reason to reshape it. A home condition estimate does not authenticate the stock or the cut.

Surface: change the light, keep the evidence

Take an evenly lit image first, then move a light so it falls across the surface from a low angle. Watch the reflection travel over the card. A crease, dent or scratch may become visible only in a particular position. A straight-on photograph with flat lighting can conceal relief even when the image is sharp. Record both the overall appearance and the angle that reveals the concern.

Distinguish what you observed from what you think caused it. Write that a line remains visible under angled light instead of declaring it a manufacturing defect without evidence. Foil patterns, print lines, scuffs and reflections can look similar in an isolated picture. A second view can show whether the mark follows the printed design or interrupts the surface. Do not wipe, polish or press the card to test a theory.

Photograph both faces under comparable conditions. A clean-looking front does not tell you whether the reverse has a wrinkle, stain or gloss change. Keep your original images and avoid aggressive exposure edits that remove the evidence. When sharing a concern, explain which photo shows it best rather than making the reviewer hunt through unrelated crops.

Centering: measure it separately

Use the free centering calculator linked below when the design has clear matching borders. Align the outer card edges and inner printed frame, then repeat on the back. Keep the camera parallel to the card. If the cut or artwork is tilted, the straight-line tool cannot describe every part of the border. Record that limitation and inspect the narrow sections in person.

PSA's earlier crucial-grading-tips article specifically discusses measuring the worst point on a tilted picture. That is a useful reason not to substitute a flattering midpoint measurement for an uneven border. A numerical result is only as good as the reference and photograph behind it. Once you have measured, return to the corner, edge and surface notes before drawing a conclusion.

Turn the inspection into a decision

Build a small record containing the card identity, whole-card front and back images, relevant close-ups and a plain-language list of concerns. Separate visible flaws from areas obscured by glare or blur. This makes it easier to request another opinion and prevents a later inspection from silently forgetting the least attractive detail. It also helps you compare the returned card with the condition you documented.
