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.

Cooling Off
The Garbologist has been digging through this one's trash.
  • 13 recorded sales · 3 in the last year · trades only a few times a year · moderate-confidence sample.
  • Following the trash: $40 → $26 → $25 → $50 → $20 — ran up to a peak of $100, then cooled back off.
  • 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.

Coin flip

Roughly a 57% gem 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 ~$21 before the $19 PSA fee (fee only - excludes shipping & insurance), ~$2 after - about even with a raw copy ($4 (est.)). A coin flip that only pays off on a high grade.
