GPK Price Guide Value iGPK Price Guide Value is a recency-weighted market value from REAL sales of this exact card+grade (recent comps count most, outliers stripped) — steadier and harder to game than a single 'last sale', which can be one lucky auction or a shill bid. When a card has few or no recent comps, we estimate transparently from its own older sales, its other grades, and comparable cards (same subject/set/rarity tier), factoring subject trend and scarcity — and we LABEL it as an estimate until real sales arrive.

🗑️ The Garbologist says…

Steady
Straight from the Garbologist's clipboard:
  • 7 recorded sales · 2 in the last year · trades only a few times a year · moderate-confidence sample.
  • Its last few sales went $97 → $120 → $120 → $120 → $100 — choppy but broadly rangebound.
  • Census check: PSA has graded 94 of this card, and only 16.0% come back a 10 — gems fairly readily.
  • Net-net, it's holding its ground — steady demand, no fireworks either way.

SAVE YOUR MONEY

Only a 16% 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 ~$49 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$-31 after - near or below a raw copy ($20 from 16 raw sales). Not worth grading unless you are confident it is a 10.
