Card # 72a
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.
  • 6 recorded sales · 2 in the last year · trades only a few times a year · moderate-confidence sample.
  • Following the trash: $71 → $38 → $100 → $75 → $30 — choppy but broadly rangebound.
  • Net-net, it's holding its ground — steady demand, no fireworks either way.
