Population and per-grade prices from our price archive · printing: holofoil. “Net if it 10s” assumes a ~£25 grading cost and is not a guarantee — the gem rate is the odds it actually grades a 10.

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.
