🗑️ The Garbologist says…

Too Few Recent Sales
The Garbologist popped the lid on this card.
  • 3 recorded sales · 2 in the last year · trades only a few times a year · limited-confidence sample.
  • The recent trail reads $48 → $240 → $252 — choppy but broadly rangebound.
  • Census check: PSA has graded 17 of this card, and only 29.4% come back a 10 — gems fairly readily.
  • None

🧬 Should I slab it?

VerdictOnly if you're confident it's a 10

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 ~$20.
Grade odds (1987 Original Series 9 cards, 2,562 PSA-graded): 10 · 34%, 9 · 39%, 8 · 13%, 7 or lower · 14%. 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.
