Is it worth grading?

Worth grading — even a PSA 9 beats raw

A PSA 10 Jam Defender [1st Edition] LON-028 sells for $301 against $5.70 raw: a $295 spread, 53× the ungraded price. Even a PSA 9 ($53.09) 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.
