Trending Up
The Garbologist sniffed around the sales pile.
  • 21 recorded sales · 6 in the last year · trades only a few times a year · moderate-confidence sample.
  • The recent trail reads $135 → $133 → $149 → $135 → $122 — a clear march higher.
  • Median moved +26% across the window ($105 → $132).
  • Heads up: the last recorded sale ($122 on 2026-10-11) landed 22% below our current value — weigh it as a single data point.
  • Census check: PSA has graded 210 of this card, and only 13.3% come back a 10 — tough to gem.
  • Net-net, the momentum points up — real buyers are paying more, more often. Not a promise, just what the garbage is telling us.

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.
