Is Plankton [Sapphire] #29 worth grading?

Entertainment · 2025 Topps Chrome SpongeBob SquarePants · full price guide →

Worth grading — even a PSA 9 beats raw

A Grade 9.5 Plankton [Sapphire] #29 sells for $116 against $19.76 raw: a $96.24 spread, 5.9× the ungraded price. Even a PSA 9 ($106) 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.

Raw (NM): $19.76
