🗑️ The Garbologist says…

No Sale In 12 Months
The Garbologist has been digging through this one's trash.
  • 3 recorded sales · 0 in the last year · trades only a few times a year · limited-confidence sample.
  • Its last few sales went $100 → $100 → $30 — choppy but broadly rangebound.
  • Heads up: the last recorded sale ($30 on 2025-06-19) landed 46% below our current value — weigh it as a single data point.
  • Census check: PSA has graded 22 of this card, and only 31.8% come back a 10 — gems fairly readily.
  • Net-net, nobody has sold this card at this grade in the last 12 months, so the trail above is history, not today's market. We don't call a direction until it sells again.

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.

🧬 Should I slab it?

Keep it raw

About 1 in 3 copies of 1988 Original Series 15 cards get a 10, and a 9 is worth $17 — less than the $92 it costs to grade. Even a 10 ($56) would leave you about -$36 after costs, not more than raw.

Expected value if gradedunder $0 (the likely slab, $30, is $62 short of the $92 all-in cost)
Raw value today$3 (from 7 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 (1988 Original Series 15 cards, 2,223 PSA-graded): 10 · 35%, 9 · 41%, 8 · 12%, 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.
