🗑️ The Garbologist says…

Trending Up
The Garbologist popped the lid on this card.
  • 11 recorded sales · 4 in the last year · trades only a few times a year · moderate-confidence sample.
  • Following the trash: $360 → $750 → $785 → $650 → $585 — a clear march higher.
  • Median moved +180% across the window ($250 → $700).
  • Heads up: the last recorded sale ($585 on 2026-09-28) landed 20% below our current value — weigh it as a single data point.
  • Census check: PSA has graded 217 of this card, and only 1.4% come back a 10 — a genuine condition rarity.
  • Net-net, the momentum points up — real buyers are paying more, more often. Not a promise, just what the garbage is telling us.

🧬 Should I slab it?

Grade it

Fewer than 1 in 50 copies of this card get a 10; across every grade, a graded copy should be worth about $602, more than the $109 it costs to grade plus the $108 raw copy you give up.

Expected value if graded$493 (after $109 all-in cost)
Raw value today$108 (from 4 raw sales)
VerdictGrade it

Grading pays even without a 10.

How these numbers work
All-in cost $109: PSA Standard tier fee $60 per card (expected $67 with PSA's upcharge if it comes back worth more than the tier allows), insured shipping to PSA ~$12, PSA insured return shipping ~$30. Sending it to your PSA Vault instead skips return shipping (vault intake and storage are free): ~$79 all-in, so a graded copy would net ~$523.
Grade odds (this card, 217 PSA-graded): 10 · 1%, 9 · 9%, 8 · 29%, 7 or lower · 61%. 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.
