🗑️ The Garbologist says…

Too Few Recent Sales
The Garbologist popped the lid on this card.
  • 6 recorded sales · 2 in the last year · trades only a few times a year · moderate-confidence sample.
  • Its last few sales went $50 → $10 → $10 → $389 → $595 — choppy but broadly rangebound.
  • Heads up: the last recorded sale ($595 on 2026-07-13) landed 1650% above our current value — weigh it as a single data point.
  • Census check: PSA has graded 137 of this card, and only 9.5% come back a 10 — tough to gem.
  • None

🧬 Should I slab it?

Only if you're confident it's a 10

Only about 1 in 11 copies of this card get a 10, and a 9 is worth $46 — less than the $92 it costs to grade.

Expected value if gradedunder $0 (the likely slab, $68, is $24 short of the $92 all-in cost)
Raw value today$70 (from 3 raw sales)
VerdictOnly if you're confident it's a 10

Break-even: you need about a 38% chance of a PSA 10 (this card: 9%).

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, 137 PSA-graded): 10 · 9%, 9 · 36%, 8 · 26%, 7 or lower · 28%. 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.
