🗑️ The Garbologist says…
Too Thin To Call
Straight from the Garbologist's clipboard:
- Nobody's actually sold this exact card and grade on record, so there's no live market to read — the price you see is a modeled estimate, not a realized sale.
- With this little to go on, the honest answer is we can't call a direction — one auction would swing the whole read.
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?
No raw price yetOnly about 1 in 3 copies of 1987 Original Series 10 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, $30, is $62 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 (all 1987 Original Series 10 cards, 2,679 PSA-graded): 10 · 33%, 9 · 38%, 8 · 14%, 7 or lower · 15%. 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.
