Price history · PSA 9
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:
- 5 recorded sales · 5 in the last year · trades about once a month · limited-confidence sample.
- Following the trash: $1,625 → $1,680 → $1,600 → $1,735 → $1,775 — holding a steady range.
- Net-net, it's holding its ground — steady demand, no fireworks either way.

🧬 Should I slab it?
Grade itOnly about 1 in 3 copies of 2025 GPK cards get a 10; across every grade, a graded copy should be worth about $2,351, more than the $299 it costs to grade plus the $788 raw copy you give up.

How these numbers work
All-in cost $299: PSA Express tier fee $199 per card (expected $242 with PSA's upcharge if it comes back worth more than the tier allows), insured shipping to PSA ~$12, PSA insured return shipping ~$45. Sending it to your PSA Vault instead skips return shipping (vault intake and storage are free): ~$254 all-in, so a graded copy would net ~$2,097.
Grade odds (all 2025 GPK cards, 5,123 PSA-graded): 10 · 29%, 9 · 51%, 8 · 14%, 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.
