🗑️ The Garbologist says…

Trending Up
The Garbologist sniffed around the sales pile.
  • 15 recorded sales · 3 in the last year · trades only a few times a year · moderate-confidence sample.
  • Its last few sales went $55 → $13 → $32 → $50 → $50 — a clear march higher.
  • Median moved +149% across the window ($20 → $50).
  • Census check: PSA has graded 96 of this card, and only 42.7% come back a 10 — gems fairly readily.
  • 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?

Only if you're confident it's a 10

About 1 in 2 copies of this card get a 10, and a 9 is worth $59 — less than the $92 it costs to grade.

Expected value if graded$1 (after $92 all-in cost)
Raw value today$4 (from 5 raw sales)
VerdictOnly if you're confident it's a 10

Break-even: you need about a 45% chance of a PSA 10 (this card: 43%).

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 ~$21.
Grade odds (this card, 96 PSA-graded): 10 · 43%, 9 · 34%, 8 · 18%, 7 or lower · 5%. 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 +10% (half the set's 3-month rise of 25%, capped at +10%).
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.
