Card # 79a
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: Liquidity read: 7 recorded sales on file (2 in the last year), trading only a few times a year — a moderate-confidence sample. The recent trail reads $20 → $12 → $6 → $25 → $11 — ran up to a peak of $25, then cooled back off. Across the trailing window the median has moved -44% ($12 vs $20). Heads up: the last recorded sale ($11 on 2025-11-10) landed 22% below our current value — weigh it as a single data point. Census check: PSA has graded 87 of this card, and only 13.8% 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.
