Card # 488a
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.

Coin flip

Roughly a 65.4% 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…

Steady
Straight from the Garbologist's clipboard: Liquidity read: 5 recorded sales on file (1 in the last year), trading only a few times a year — a limited-confidence sample. Following the trash: $13 → $37 → $52 → $47 → $21 — choppy but broadly rangebound. 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.
