Population and per-grade prices from our price archive · printing: normal. Grading economics are hidden for this card: fewer than 50 slabs graded, so an uplift figure wouldn’t be meaningful.

The HitBinder Price is our trust-weighted estimate (archive blend), shown in your chosen display currency (switch it top-right); PSA 10 reflects recent graded sales. Indicative, not quotes — condition, grading and printing variance apply.
