Price history · PSA 10
On-the-record sales go back as far as PSA reports them — late 2017 for GPK — plus eBay-tracked and raw sales as they land.
🗑️ The Garbologist says…
Cooling Off
Straight from the Garbologist's clipboard:
- 12 recorded sales · 3 in the last year · trades only a few times a year · moderate-confidence sample.
- Following the trash: $20 → $16 → $18 → $18 → $30 — a steady drift lower.
- Median moved -49% across the window ($37 → $19).
- Census check: PSA has graded 33 of this card, and only 54.5% come back a 10 — gems fairly readily.
- Net-net, the heat is coming off — recent sales are softening. Could be a breather, could be a top; the trash doesn't say which.

🧬 Should I slab it?
Keep it rawOnly about 1 in 3 copies of 1987 Original Series 9 cards get a 10, and a 9 is worth $15 — less than the $92 it costs to grade. Even a 10 ($32) would leave you about -$60 after costs, not more than raw.
Expected value if gradedunder $0 (the likely slab, $20, is $72 short of the $92 all-in cost)

VerdictKeep it raw
Even a PSA 10 would not beat the raw value.

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 (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.
