Card # 349a
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.

Roughly a 33.3% gem rate on this card's own PSA pop. After the $19 grade it's about even with a raw copy — a coin flip that only pays off on a high grade.

🗑️ The Garbologist says…

Cooling Off
Straight from the Garbologist's clipboard: Liquidity read: 3 recorded sales on file (0 in the last year), trading only a few times a year — a limited-confidence sample. Its last few sales went $16 → $9 → $8 — a steady drift lower. Across the trailing window the median has moved -48% ($8 vs $16). 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.
