Should you grade it?
Whether a Professor Oak's New Theory is worth grading comes down to the grade it would actually get, and for many cards a PSA 10 is worth several times a 9 (see what PSA 10 Pokémon cards sell for). Centering decides the ceiling: PSA allows about 55/45 on the front for a 10 and 60/40 for a 9. Check yours with the PSA centering tool, or scan it for a full grade estimate and the grade-or-keep-raw verdict with fees counted.
