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…
Steady
The Garbologist has been digging through this one's trash. Liquidity read: 3 recorded sales on file (3 in the last year), trading every few months — a limited-confidence sample. Its last few sales went $13 → $30 → $10 — choppy but broadly rangebound. Heads up: the last recorded sale ($10 on 2026-04-25) landed 25% below our current value — weigh it as a single data point. Net-net, it's holding its ground — steady demand, no fireworks either way.
Automated analysis generated from this card’s real recorded sales and PSA population data — no opinions, no predictions guaranteed. Entertainment and research only, not financial advice.
