Is grading worth it — at the real gem rate?
Buying raw at $37 and grading: a 10 nets ~$315, a 9 nets ~$46. At this card's real 30% gem rate, the expected outcome is +$65 after a ~$25 grading fee — assuming a clean copy that grades 9 or 10. Below-9 outcomes make it worse; a sharp eye for centering and surface is what beats these odds.
