🗑️ The Garbologist says…
Too Few Recent Sales
The Garbologist popped the lid on this card.
- 10 recorded sales · 2 in the last year · trades only a few times a year · moderate-confidence sample.
- The recent trail reads $10 → $27 → $39 → $30 → $40 — choppy but broadly rangebound.
- Census check: PSA has graded 389 of this card, and only 7.2% come back a 10 — tough to gem.
- None

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 ~$62.
Grade odds (this card, 389 PSA-graded): 10 · 7%, 9 · 32%, 8 · 27%, 7 or lower · 34%. 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.
