🗑️ The Garbologist says…

Cooling Off
The Garbologist popped the lid on this card.
  • 15 recorded sales · 4 in the last year · trades only a few times a year · moderate-confidence sample.
  • Its last few sales went $75 → $103 → $185 → $140 → $134 — ran up to a peak of $185, then cooled back off.
  • Median moved -13% across the window ($102 → $89).
  • Heads up: the last recorded sale ($134 on 2026-11-06) landed 23% below our current value — weigh it as a single data point.
  • Net-net, the heat is coming off — recent sales are softening. Could be a breather, could be a top; the trash doesn't say which.

🧬 Should I slab it?

Grade it

Only about 1 in 8 copies of this card get a 10; across every grade, a graded copy should be worth about $256, more than the $92 it costs to grade plus the $20 raw copy you give up.

Expected value if graded$164 (after $92 all-in cost)
Raw value today$20 (from 9 raw sales)
VerdictGrade it

Grading pays even without a 10.

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 ~$184.
Grade odds (this card, 76 PSA-graded): 10 · 12%, 9 · 75%, 8 · 12%, 7 or lower · 1%. 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.
