🗑️ The Garbologist says…
No Sale In 12 Months
The Garbologist popped the lid on this card.
- 4 recorded sales · 0 in the last year · trades only a few times a year · limited-confidence sample.
- Following the trash: $8 → $19 → $25 → $25 — choppy but broadly rangebound.
- Census check: PSA has graded 96 of this card, and only 15.6% 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 6 copies of this card get a 10, and a 9 is worth $58 — less than the $92 it costs to grade. Even a 10 ($107) would leave you about $15 after costs, not more than raw.
Expected value if gradedunder $0 (the likely slab, $48, is $44 short of the $92 all-in cost)

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 (this card, 96 PSA-graded): 10 · 16%, 9 · 29%, 8 · 26%, 7 or lower · 29%. 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.
