Card # 8a
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. Liquidity read: 55 recorded sales on file (53 in the last year), trading roughly every couple of weeks — a high-confidence sample. Following the trash: $580 → $502 → $464 → $710 → $390 — ran up to a peak of $800, then cooled back off. Heads up: the last recorded sale ($390 on 2026-06-14) landed 30% below our current value — weigh it as a single data point. 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.
