Corners, edges, surface and centering
Learn to separate four visible areas of card condition and interpret their evidence without confusing defects, reflections or camera perspective.
Visible condition is commonly organised into four areas: centering, corners, edges and surface. Keeping them separate prevents an overall impression from replacing evidence. It also explains why two cards that look similar at first can have different limiting factors.
Centering: the position of the design
Centering describes how the printed design sits within the card’s physical boundaries. It is considered horizontally and vertically on both front and back. It is not wear, and it should not be measured from a tilted photograph.
The rectangle must be found and perspective corrected first. If one edge is closer to the camera, it will appear larger even though the print has not changed. That is why a reliable perspective and centering capture comes before any ratio.
Corners: four small areas with dense detail
A corner can show rounding, material loss, a bend, layer separation or a small impact. A useful observation identifies which corner, which side and which frame shows it best. “Weak corners” says less than a located, visible change.
Blur can also make a corner look rounded. If the outline changes between frames or falls outside the focus plane, confidence should decrease. A precise number cannot compensate for a corner that is not visible.
Edges: continuity around the card
Edges should be reviewed along the whole perimeter. They can show light or dark points, roughness, small notches, ink loss or separation of the stock. Front and back may show different evidence, so each side should be traced independently.
Frontal light helps with continuity and colour. Low-angle light can reveal relief, but it also creates strong highlights. Combining both phases lowers the risk of treating a line of light as actual wear.
Surface: print, gloss and visible relief
Surface evidence includes scratches, scuffing, stains, print lines, creases, visible indentations and changes in gloss. Not all of it comes from handling; some features may come from printing or finish. A responsible visual estimate describes what is visible without inventing its cause.
Raking light is useful because a surface change interrupts the path of the light. Evidence becomes stronger when it appears from more than one angle and remains in the same location. If it exists only in one bright frame, it may be glare.
Turning observations into a report
PSA, CGC and Beckett publish their own scales and consider these areas in different ways. BGT does not copy their certificates or present an official equivalence. It keeps versioned rubrics private and shows a conservative BGT Grade beside its own subgrades and evidence.
Read the marked areas before the large number. The guide to reading a visual report explains how severity, side, frame and confidence work together. When a category lacks sufficient coverage, recapture is more honest than assuming it is perfect.
