🗑️ The Garbologist says…

Too Few Recent Sales
The Garbologist popped the lid on this card.
  • 19 recorded sales · 2 in the last year · trades only a few times a year · moderate-confidence sample.
  • Its last few sales went $368 → $480 → $339 → $725 → $502 — choppy but broadly rangebound.
  • Census check: PSA has graded 481 of this card, and only 7.9% 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 13 copies of this card get a 10. A 10 is worth $547, but after the $92 cost it barely beats the $11 raw copy.

Expected value if graded$14 (after $92 all-in cost)
Raw value today$11 (from 120 raw sales)
VerdictOnly if you're confident it's a 10

Break-even: you need about a 7% chance of a PSA 10 (this card: 8%).

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 ~$34.
Grade odds (this card, 481 PSA-graded): 10 · 8%, 9 · 28%, 8 · 32%, 7 or lower · 32%. 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.
