🗑️ The Garbologist says…
Too Few Recent Sales
The Garbologist popped the lid on this card.
- 5 recorded sales · 1 in the last year · trades only a few times a year · limited-confidence sample.
- Following the trash: $33 → $14 → $12 → $30 → $50 — choppy but broadly rangebound.
- Heads up: the last recorded sale ($50 on 2026-10-22) landed 117% above our current value — weigh it as a single data point.
- None

🧬 Should I slab it?
Keep it rawAbout 5 in 10 copies of 1988 Original Series 12 cards get a 10, and a 9 is worth $23 — less than the $92 it costs to grade. Even a 10 ($54) would leave you about -$38 after costs, not more than raw.
Expected value if gradedunder $0 (the likely slab, $38, is $54 short of the $92 all-in cost)

VerdictKeep it raw
Even a PSA 10 would not beat the raw value.

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 (1988 Original Series 12 cards, 1,976 PSA-graded): 10 · 52%, 9 · 36%, 8 · 7%, 7 or lower · 5%. 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.
