🗑️ The Garbologist says…
Cooling Off
The Garbologist has been digging through this one's trash.
- 14 recorded sales · 4 in the last year · trades only a few times a year · moderate-confidence sample.
- Following the trash: $50 → $25 → $20 → $19 → $26 — a steady drift lower.
- Median moved -42% across the window ($45 → $26).
- Heads up: the last recorded sale ($26 on 2026-03-18) landed 28% below our current value — weigh it as a single data point.
- Net-net, the heat is coming off — recent sales are softening. Could be a breather, could be a top; the trash doesn't say which.

🧬 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 $15 — less than the $92 it costs to grade. Even a 10 ($36) would leave you about -$56 after costs, not more than raw.
Expected value if gradedunder $0 (the likely slab, $25, is $67 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.
