Worth grading — even a PSA 9 beats raw

A PSA 9 Seaking sells for $149 against $1.04 raw: a $148 spread, 144× the ungraded price. Even a PSA 9 ($149) clears the raw price after an economy-tier ~$25 fee, so a near-miss still comes out ahead. Centering is the usual reason a clean copy misses the 10 — measure it before you submit.

Grading Seaking — FAQ

Is Seaking worth grading?

A PSA 9 Seaking sells for $149 against $1.04 raw: a $148 spread, 144× the ungraded price. Even a PSA 9 ($149) clears the raw price after an economy-tier ~$25 fee, so a near-miss still comes out ahead. Centering is the usual reason a clean copy misses the 10 — measure it before you submit.

What centering does Seaking need for a CGC 10?

CGC publishes 55/45 front and 75/25 back centering as the tolerance for a 10 (Gem Mint). Off-center copies are capped below the top grade regardless of surface — measure yours before paying the fee.

Is your Pokémon card centered well enough to grade?

Centering makes or breaks a PSA 10. Scan any card with Midpoint to measure its exact centering, get a grade estimate, and see what your copy is actually worth.
