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
Straight from the Garbologist's clipboard:
- 4 recorded sales · 0 in the last year · trades only a few times a year · limited-confidence sample.
- Its last few sales went $56 → $50 → $50 → $31 — choppy but broadly rangebound.
- Heads up: the last recorded sale ($31 on 2025-01-19) landed 37% below our current value — weigh it as a single data point.
- 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.

🧬 Should I slab it?
Keep it rawAbout 5 in 10 copies of 1988 Original Series 13 cards get a 10, and a 9 is worth $17 — less than the $92 it costs to grade. Even a 10 ($49) would leave you about -$43 after costs, not more than raw.
Expected value if gradedunder $0 (the likely slab, $34, is $58 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 (1988 Original Series 13 cards, 1,689 PSA-graded): 10 · 54%, 9 · 33%, 8 · 6%, 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.
