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…
No Sale In 12 Months
The Garbologist sniffed around the sales pile.
- 7 recorded sales · 0 in the last year · trades only a few times a year · moderate-confidence sample.
- Following the trash: $128 → $108 → $200 → $144 → $200 — choppy but broadly rangebound.
- Heads up: the last recorded sale ($200 on 2025-10-16) landed 20% below our current value — weigh it as a single data point.
- Census check: PSA has graded 154 of this card, and only 13.0% come back a 10 — tough to gem.
- Net-net, nobody has sold this card at this grade in the last 12 months, so the trail above is history, not today's market. We don't call a direction until it sells again.

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 ~$0.
Grade odds (this card, 154 PSA-graded): 10 · 13%, 9 · 34%, 8 · 21%, 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.
