🗑️ The Garbologist says…

No Sale In 12 Months
The Garbologist sniffed around the sales pile.
  • 3 recorded sales · 0 in the last year · trades only a few times a year · limited-confidence sample.
  • The recent trail reads $18 → $10 → $10 — choppy but broadly rangebound.
  • Heads up: the last recorded sale ($10 on 2025-10-24) landed 45% below our current value — weigh it as a single data point.
  • 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 $19 — less than the $92 it costs to grade.

Expected value if gradedunder $0 (the likely slab, $45, is $47 short of the $92 all-in cost)
Raw value today$5 (from 12 raw sales)
VerdictKeep it raw

Break-even: you need about a 98% chance of a PSA 10 (1988 Original Series 15 cards: 35%).

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.
