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…

Too Thin To Call
Straight from the Garbologist's clipboard:
  • Only 1 recorded sale on the books — not enough for a trend without kidding ourselves. The last one changed hands at $66 on 2020-05-28.
  • With this little to go on, the honest answer is we can't call a direction — one auction would swing the whole read.

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.

About a 4% 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 ~$1,547 before the $599 PSA fee (fee only - excludes shipping & insurance), ~$948 after, vs a raw copy around $93 (est.). Grading pencils out here, especially if you hit the $19,126 ten.
