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
The Garbologist has been digging through this one's trash.
- 4 recorded sales · 3 in the last year · trades only a few times a year · limited-confidence sample.
- Its last few sales went $22 → $13 → $30 → $10 — choppy but broadly rangebound.
- Heads up: the last recorded sale ($10 on 2026-04-25) landed 73% below our current value — weigh it as a single data point.
- Net-net, it's holding its ground — steady demand, no fireworks either way.

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 (all 2023 Intergoolactic Mayhem cards, 1,047 PSA-graded): 10 · 52%, 9 · 32%, 8 · 11%, 7 or lower · 5%. 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.
