🗑️ The Garbologist says…

Too Few Recent Sales
The Garbologist has been digging through this one's trash.
  • 7 recorded sales · 1 in the last year · trades only a few times a year · moderate-confidence sample.
  • Its last few sales went $71 → $108 → $53 → $36 → $40 — choppy but broadly rangebound.
  • Heads up: the last recorded sale ($40 on 2026-07-29) landed 27% below our current value — weigh it as a single data point.
  • None

🧬 Should I slab it?

Keep it raw

Only about 1 in 3 copies of 1988 Original Series 15 cards get a 10, and a 9 is worth $16 — less than the $92 it costs to grade. Even a 10 ($55) would leave you about -$37 after costs, not more than raw.

Expected value if gradedunder $0 (the likely slab, $28, is $64 short of the $92 all-in cost)
Raw value today$4 (from 17 raw sales)
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 (all 1988 Original Series 15 cards, 4,079 PSA-graded): 10 · 35%, 9 · 41%, 8 · 13%, 7 or lower · 11%. 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.
