Worth grading — even a PSA 9 beats raw

A CGC 10 Kingdra sells for $500 against $37.09 raw: a $463 spread, 13× the ungraded price. Even a PSA 9 ($75.01) 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 Kingdra — FAQ

Is Kingdra worth grading?

A CGC 10 Kingdra sells for $500 against $37.09 raw: a $463 spread, 13× the ungraded price. Even a PSA 9 ($75.01) 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 Kingdra 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.

What gem rate makes grading Kingdra break even?

At a standard ~$50 fee, submitting Kingdra breaks even when it gems about 3% of the time (a miss assumed to sell at the PSA 9 price of $75.01).
