SIDNEY KIDNEY ACTIVE
🗑️ The Garbologist says…
Steady- 10 recorded sales · 2 in the last year · trades only a few times a year · moderate-confidence sample.
- Following the trash: $8 → $9 → $10 → $12 → $20 — choppy but broadly rangebound.
- Census check: PSA has graded 79 of this card, and only 13.9% come back a 10 — tough to gem.
- 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.

SAVE YOUR MONEYOnly a 36% gem rate on the 1987 GPK PSA pop (all sets that year) - graded pop is self-selected (best copies get submitted), so a random raw likely grades lower. Expected ~$31 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$-49 after - near or below a raw copy ($2 from 12 raw sales). Not worth grading unless you are confident it is a 10.
Probability-weighted across grades using PSA population (1987 GPK, all sets) as a proxy for cut & print quality, minus the grading fee. A guide, not a guarantee — centering and eye-appeal on your specific copy decide the grade.
