🗑️ The Garbologist says…

Trending Up
The Garbologist has been digging through this one's trash.
  • 8 recorded sales · 3 in the last year · trades only a few times a year · moderate-confidence sample.
  • Its last few sales went $29 → $93 → $115 → $90 → $90 — a clear march higher.
  • Median moved +173% across the window ($33 → $92).
  • Census check: PSA has graded 153 of this card, and only 9.8% 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.

Automated analysis generated from this card’s real recorded sales and PSA population data — no opinions, no predictions guaranteed. Entertainment and research only, not financial advice.

Grade it

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 ~$128.
Grade odds (this card, 156 PSA-graded): 10 · 10%, 9 · 25%, 8 · 26%, 7 or lower · 39%. 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.
