🗑️ The Garbologist says…
Too Few Recent Sales
The Garbologist popped the lid on this card.
- 9 recorded sales · 1 in the last year · trades only a few times a year · moderate-confidence sample.
- The recent trail reads $47 → $25 → $26 → $25 → $22 — choppy but broadly rangebound.
- Heads up: the last recorded sale ($22 on 2026-03-18) landed 35% below our current value — weigh it as a single data point.
- None

How these numbers work
All-in cost $92: PSA Standard tier fee $60 per card, insured shipping to PSA ~$12, PSA insured return shipping ~$20. Sending it to your PSA Vault instead skips return shipping (vault intake and storage are free): ~$72 all-in, so a graded copy would net ~under $0.
Grade odds (all 1988 Original Series 13 cards, 1,948 PSA-graded): 10 · 54%, 9 · 32%, 8 · 7%, 7 or lower · 7%. People send their best copies, so a random raw copy usually grades a bit lower.
Values when it comes back (~95 days, about Feb 12, 2027): today's values (the set has no clear 3-month trend).
Expected value if graded = each grade's chance × its value, minus the all-in cost. A guide, not a guarantee — centering and corners on your copy decide the grade.
