Card # 38a
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…

Trending Up
The Garbologist sniffed around the sales pile.
  • 34 recorded sales · 13 in the last year · trades every few months · moderate-confidence sample.
  • Its last few sales went $41 → $44 → $45 → $65 → $80 — a clear march higher.
  • Median moved +30% across the window ($46 → $52).
  • Heads up: the last recorded sale ($80 on 2026-07-11) landed 28% above our current value — weigh it as a single data point.
  • Census check: PSA has graded 496 of this card, and only 8.7% come back a 10 — tough to gem.
  • Net-net, the momentum points up — real buyers are paying more, more often. Not a promise, just what the garbage is telling us.

🧬 Should I slab it?

SLAB IT

About a 9% 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 ~$72 before the $29 PSA fee (fee only - excludes shipping & insurance), ~$43 after, vs a raw copy around $9 (est.). Grading pencils out here, especially if you hit the $269 ten.
