🧬 Should I slab it?

BORDERLINE

Roughly a 47% gem rate on this card's own PSA pop - graded pop is self-selected (best copies get submitted), so a random raw likely grades lower. Expected ~$301 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$221 after - about even with a raw copy ($188 from 6 raw sales). A coin flip that only pays off on a high grade.
