🗑️ The Garbologist says…
No Sale In 12 Months
The Garbologist has been digging through this one's trash.
- 4 recorded sales · 0 in the last year · trades only a few times a year · limited-confidence sample.
- The recent trail reads $29 → $86 → $65 → $125 — choppy but broadly rangebound.
- 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.

Expected value if gradedunder $0 (the likely slab, $47, is $45 short of the $92 all-in cost)

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 Diecut cards, 1,262 PSA-graded): 10 · 33%, 9 · 42%, 8 · 14%, 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.
