🗑️ The Garbologist says…

Trending Up
The Garbologist has been digging through this one's trash.
  • 16 recorded sales · 4 in the last year · trades only a few times a year · moderate-confidence sample.
  • Its last few sales went $390 → $700 → $590 → $788 → $832 — a clear march higher.
  • Median moved +219% across the window ($202 → $645).
  • 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.

🧬 Should I slab it?

Grade it

Only about 1 in 8 copies of this card get a 10; across every grade, a graded copy should be worth about $189, more than the $92 it costs to grade plus the $15 raw copy you give up.

Expected value if graded$97 (after $92 all-in cost)
Raw value today$15 (from 23 raw sales)
VerdictGrade it

Break-even: you need about a 1% chance of a PSA 10 (this card: 13%).

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.
