Card # 100a
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.

Trending Up
The Garbologist popped the lid on this card. Liquidity read: 46 recorded sales on file (14 in the last year), trading every few months — a high-confidence sample. The recent trail reads $104 → $90 → $100 → $120 → $171 — a clear march higher. Across the trailing window the median has moved +125% ($95 vs $42). Heads up: the last recorded sale ($171 on 2026-06-27) landed 32% above our current value — weigh it as a single data point. Census check: PSA has graded 234 of this card, and only 33.3% come back a 10 — gems fairly readily. Net-net, the momentum points up — real buyers are paying more, more often. Not a promise, just what the garbage is telling us.
