🗑️ The Garbologist says…

Steady
The Garbologist sniffed around the sales pile.
  • 6 recorded sales · 2 in the last year · trades only a few times a year · moderate-confidence sample.
  • Following the trash: $22 → $18 → $28 → $20 → $20 — choppy but broadly rangebound.
  • Heads up: the last recorded sale ($20 on 2026-09-02) landed 20% below our current value — weigh it as a single data point.
  • Census check: PSA has graded 495 of this card, and only 6.7% come back a 10 — tough to gem.
  • Net-net, it's holding its ground — steady demand, no fireworks either way.

🧬 Should I slab it?

Grade it

Only about 1 in 15 copies of this card get a 10; across every grade, a graded copy should be worth about $142, more than the $92 it costs to grade plus the $10 raw copy you give up.

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 ~$70.
Grade odds (this card, 495 PSA-graded): 10 · 7%, 9 · 24%, 8 · 36%, 7 or lower · 34%. 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.
