Card # 508b
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 sniffed around the sales pile. Liquidity read: 4 recorded sales on file (1 in the last year), trading only a few times a year — a limited-confidence sample. Following the trash: $16 → $20 → $10 → $28 — choppy but broadly rangebound. Census check: PSA has graded 14 of this card, and only 35.7% come back a 10 — gems fairly readily. 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.
