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
The Garbologist sniffed around the sales pile.
  • 22 recorded sales · 3 in the last year · trades only a few times a year · moderate-confidence sample.
  • Following the trash: $176 → $414 → $399 → $320 → $405 — choppy but broadly rangebound.
  • Census check: PSA has graded 244 of this card, and only 23.0% come back a 10 — gems fairly readily.
  • Net-net, it's holding its ground — steady demand, no fireworks either way.

Automated analysis generated from this card’s real recorded sales and PSA population data — no opinions, no predictions guaranteed. Entertainment and research only, not financial advice.

🧬 Should I slab it?

SLAB IT

About a 23% gem (PSA 10) 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 value ~$164 before the $29 PSA fee (fee only - excludes shipping & insurance), ~$135 after, vs a raw copy around $18 (est.). Grading pencils out here, especially if you hit the $405 ten.
