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…
Steady
Straight from the Garbologist's clipboard:
- 7 recorded sales · 2 in the last year · trades only a few times a year · moderate-confidence sample.
- Its last few sales went $97 → $120 → $120 → $120 → $100 — choppy but broadly rangebound.
- Census check: PSA has graded 96 of this card, and only 15.6% come back a 10 — gems fairly readily.
- Net-net, it's holding its ground — steady demand, no fireworks either way.

🧬 Should I slab it?
Keep it rawOnly about 1 in 6 copies of this card get a 10, and a 9 is worth $58 — less than the $92 it costs to grade. Even a 10 ($106) would leave you about $14 after costs, not more than raw.
Expected value if gradedunder $0 (the likely slab, $48, is $44 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 (this card, 96 PSA-graded): 10 · 16%, 9 · 29%, 8 · 26%, 7 or lower · 29%. People send their best copies, so a random raw copy usually grades a bit lower.
Values when it comes back (~95 days, about Feb 13, 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.
