Price history · PSA 8.5
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…
Too Thin To Call
The Garbologist sniffed around the sales pile.
- Only 1 recorded sale on the books — not enough for a trend without kidding ourselves. The last one changed hands at $8 on 2018-06-25.
- With this little to go on, the honest answer is we can't call a direction — one auction would swing the whole read.

🧬 Should I slab it?
Only if you're confident it's a 10Only about 1 in 13 copies of this card get a 10. A 10 is worth $547, but after the $92 cost it barely beats the $11 raw copy.
Expected value if graded$14 (after $92 all-in cost)
Raw value today$11 (from 120 raw sales)
VerdictOnly if you're confident it's a 10
Break-even: you need about a 7% chance of a PSA 10 (this card: 8%).

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 ~$34.
Grade odds (this card, 481 PSA-graded): 10 · 8%, 9 · 28%, 8 · 32%, 7 or lower · 32%. 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.
