🗑️ The Garbologist says…
Too Thin To Call
Straight from the Garbologist's clipboard:
- Only 1 recorded sale on the books — not enough for a trend without kidding ourselves. The last one changed hands at $12 on 2026-09-23.
- With this little to go on, the honest answer is we can't call a direction — one auction would swing the whole read.

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 ~$117.
Grade odds (this card, 210 PSA-graded): 10 · 13%, 9 · 31%, 8 · 30%, 7 or lower · 25%. 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.
