Garbage Pail Kids
TCA Value iTCAxis 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…

Cooling Off
Straight from the Garbologist's clipboard:
  • 53 recorded sales · 5 in the last year · trades every few months · high-confidence sample.
  • Following the trash: $90 → $110 → $28 → $140 → $106 — ran up to a peak of $140, then cooled back off.
  • Median moved -16% across the window ($95 → $80).
  • Heads up: the last recorded sale ($106 on 2025-12-14) landed 27% below our current value — weigh it as a single data point.
  • Census check: PSA has graded 506 of this card, and only 5.1% come back a 10 — tough to gem.
  • Net-net, the heat is coming off — recent sales are softening. Could be a breather, could be a top; the trash doesn't say which.

Worth grading

About a 5% 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 ~$126 before the $79 PSA fee (fee only - excludes shipping & insurance), ~$47 after, vs a raw copy around $10 (est.). Grading pencils out here, especially if you hit the $1,018 ten.
