The Surface Pitting Survival Guide: Protecting Your Prizm Assets

Published 2026-01-28

It looks perfect to the naked eye. Then it comes back as a PSA 8. Surface "pitting" is the silent assassin of modern card grading.

What is Pitting?

Pitting refers to microscopic craters or voids in the chromium layer of a card. During the manufacturing process, when the foil layer is applied to the card stock, tiny air bubbles or dust particles can get trapped. When the laminate seals, these bubbles burst or settle, leaving a tiny "pit."

Unlike a scratch (which is a line) or a dimple (which is a depression), pitting looks like tiny speckles of "missing" gloss.

How Graders Spot It

Pitting is almost invisible under direct, flat light. Graders find it using Raking Light. They tilt the card at an extreme angle (nearly 180 degrees flat) under a high-intensity halogen lamp.

In this lighting condition, the smooth surface of the card reflects light uniformly. However, a "pit" disrupts the reflection, appearing as a tiny black pinprick or a sparkling "star" where the light is scattered.

The Prizm Pandemic

The 2020-2022 Panini Prizm sets are notorious for this issue. QC standards dropped during the boom, and "sheet pitting" became common. Entire runs of cards have this defect straight out of the pack.

Grading Impact Scale

  • Minor Pitting: 1-2 tiny specs visible only under magnification. Maximum Grade: PSA 9 / BGS 9.
  • Moderate Pitting: A cluster of specs visible to the naked eye in raking light. Maximum Grade: PSA 8.
  • Heavy Pitting: Widespread "sandpaper" texture. Maximum Grade: PSA 6/7.

Can You Fix It?

No. Unlike wax or fingerprints, pitting is a structural defect in the card material. You cannot polish it out. Any attempt to "buff" pitting will simply remove the surrounding gloss, creating a larger dull spot that counts as surface damage.

Survival Strategy

If you see pitting, do not grade. Sell the card raw with full disclosure ("minor surface issues"). A raw card often sells for more than a PSA 7 slab, which alerts buyers to the defect.
