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…
No Sale In 12 Months
The Garbologist sniffed around the sales pile.
- 3 recorded sales · 0 in the last year · trades only a few times a year · limited-confidence sample.
- Its last few sales went $8 → $8 → $8 — holding a steady range.
- Heads up: the last recorded sale ($8 on 2025-10-28) landed 43% below our current value — weigh it as a single data point.
- Census check: PSA has graded 11 of this card, and only 27.3% come back a 10 — gems fairly readily.
- 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 rawOnly about 1 in 3 copies of 1988 Original Series 15 cards get a 10, and a 9 is worth $14 — less than the $92 it costs to grade. Even a 10 ($74) would leave you about -$18 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 (all 1988 Original Series 15 cards, 4,079 PSA-graded): 10 · 35%, 9 · 41%, 8 · 13%, 7 or lower · 11%. People send their best copies, so a random raw copy usually grades a bit lower.
Values when it comes back (~95 days, about Feb 13, 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.
