SGC 3 is the most actively traded grade in the recorded sample, with 3 sales and a recorded median around $160.

Compare the likely raw value, grading fees, shipping, and the median for the grade you realistically expect. Grading is easier to justify when the expected graded value comfortably clears those costs.
