Key ideas in Pokémon Card Collecting Traps
- Overhead diffuse lighting bounces straight back and washes out shallow card depressions.
- Raking light casts shadows inside foil micro-scratches and shallow print indentations.
- Tilting a single directional light source at a shallow angle highlights surface texture flaws.
- Dull factory cutting dies chip the outer ink layer, exposing raw silver foil along edges.
- Grading services evaluate physical condition objectively without discounting factory defects.
- Roller marks create uniform indented machine tracks that span across the card.
- Factory print lines appear as dead-straight missing ink streaks under the clear gloss.
- Scratches physically gouge through the gloss finish and follow irregular paths.
- Top-tier Gem Mint grades require front centering to stay within strict 60/40 or 55/45 limits.
- A 75/25 border ratio automatically caps the final grade regardless of flawless surface foil.
- The classic dark blue border creates maximum contrast against white edge and corner dings.
- Intricate holographic front artwork distracts buyers from spotting subtle pressure dents.
- Checking the back first prevents emotional attachment to flashy front illustration art.
- A PSA 9 on modern cards usually sells close to raw market price.
- Grading fee, two-way insured shipping, and selling fees stack against final sale value.
- Unless a modern card scores a 10, total submission overhead creates a net loss versus selling raw.
