🗑️ The Garbologist says…

Too Few Recent Sales
The Garbologist sniffed around the sales pile.
  • 11 recorded sales · 2 in the last year · trades only a few times a year · moderate-confidence sample.
  • The recent trail reads $13 → $20 → $10 → $20 → $22 — ran up to a peak of $51, then cooled back off.
  • Census check: PSA has graded 65 of this card, and only 46.2% come back a 10 — gems fairly readily.
  • None

🧬 Should I slab it?

Keep it raw

About 1 in 2 copies of this card get a 10, and a 9 is worth $20 — less than the $92 it costs to grade. Even a 10 ($48) would leave you about -$44 after costs, not more than raw.

Expected value if gradedunder $0 (the likely slab, $31, is $61 short of the $92 all-in cost)
Raw value today$2 (from 17 raw sales)
VerdictKeep it raw

Even a PSA 10 would not beat the raw value.

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 ~under $0.
Grade odds (this card, 65 PSA-graded): 10 · 46%, 9 · 28%, 8 · 18%, 7 or lower · 8%. 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.
