🗑️ The Garbologist says…

Too Few Recent Sales
Straight from the Garbologist's clipboard:
  • 3 recorded sales · 1 in the last year · trades only a few times a year · limited-confidence sample.
  • Its last few sales went $36 → $16 → $15 — choppy but broadly rangebound.
  • Census check: PSA has graded 31 of this card, and only 67.7% come back a 10 — gems fairly readily.
  • None

🧬 Should I slab it?

No raw price yet

About 5 in 10 copies of 1988 Original Series 13 cards get a 10. A graded copy should be worth about $0 after the $92 cost; we have no raw sale of this card to compare.

Expected value if gradedunder $0 (the likely slab, $26, is $66 short of the $92 all-in cost)

Even a PSA 10 would not beat the 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 (all 1988 Original Series 13 cards, 1,948 PSA-graded): 10 · 54%, 9 · 32%, 8 · 7%, 7 or lower · 7%. 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.
