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.

Trending Up
The Garbologist sniffed around the sales pile.
  • 7 recorded sales · 1 in the last year · trades only a few times a year · moderate-confidence sample.
  • The recent trail reads $486 → $350 → $741 → $1,175 → $878 — a clear march higher.
  • Median moved +41% across the window ($575 → $810).
  • Census check: PSA has graded 237 of this card, and only 10.5% 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 7% 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 ~$190 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$110 after, vs a raw copy around $20 from 18 raw sales. Grading pencils out here, especially if you hit the $1,086 ten.
