How to prep a raw card for grading

Graders do not clean cards. Whatever you submit is what gets graded, so the five minutes you spend before sealing the envelope matter more than most collectors think. Here is the routine we use on every submission.

1. Work clean

Wash your hands, then put on lint-free gloves anyway. Work over a soft mat in good light. Skin oil is the quietest way to turn a surface 10 into a 9.

2. Check centering first

Centering is the one flaw you cannot fix, so measure it before you spend time on anything else. A centering tool gives you the left-right and top-bottom ratios in seconds. If the card measures worse than 60/40, decide whether the grade you can reach is worth the fee.

3. Deal with warp

Modern cards curl, especially foils. A card press flattens them slowly and evenly with no heat. Give a warped card a few days in the press before submission. Never iron, never stack books on a loose card.

4. Clean the surface, gently

Use an air blower to lift dust, then a dry microfiber cloth in one direction with almost no pressure. Nothing wet, ever. If a mark does not lift with a dry cloth, it is part of the card now.

5. Inspect like a grader

Under a loupe, check the four corners, the edges front and back, and the surface at an angle to the light. You are looking for whitening, print lines, and scratches. Grade it yourself honestly before paying someone else to.

6. Sleeve and ship tight

Penny sleeve, then a semi-rigid holder, opening up. Pack so nothing moves. Cards grade the way they arrive.

Our grading prep kit bundles the centering tool, gloves, loupe, cloth, and blower in one case, and the card press handles the warp. Both live in the Grading prep collection.
