🗑️ The Garbologist says…

Cooling Off
The Garbologist has been digging through this one's trash.
  • 9 recorded sales · 5 in the last year · trades only a few times a year · moderate-confidence sample.
  • Following the trash: $30 → $20 → $19 → $20 → $17 — ran up to a peak of $30, then cooled back off.
  • Median moved -11% across the window ($22 → $20).
  • Census check: PSA has graded 526 of this card, and only 4.6% come back a 10 — a genuine condition rarity.
  • 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?

Only if you're confident it's a 10

Only about 1 in 22 copies of this card get a 10. A 10 is worth $607, but after the $92 cost it barely beats the $13 raw copy.

Expected value if graded$7 (after $92 all-in cost)
Raw value today$13 (from 163 raw sales)
VerdictOnly if you're confident it's a 10

Break-even: you need about a 6% chance of a PSA 10 (this card: 5%).

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 ~$27.
Grade odds (this card, 533 PSA-graded): 10 · 5%, 9 · 27%, 8 · 28%, 7 or lower · 41%. 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.
