The Garbologist sniffed around the sales pile.
  • 37 recorded sales · 11 in the last year · trades every few months · moderate-confidence sample.
  • Following the trash: $17 → $50 → $25 → $32 → $44 — a clear march higher.
  • Median moved +32% across the window ($12 → $25).
  • Heads up: the last recorded sale ($44 on 2026-10-16) landed 42% above our current value — weigh it as a single data point.
  • Census check: PSA has graded 171 of this card, and only 33.9% 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?

Keep it raw

Only about 1 in 3 copies of this card get a 10, and a 9 is worth $34 — less than the $92 it costs to grade. Even a 10 ($73) would leave you about -$19 after costs, not more than raw.

Expected value if gradedunder $0 (the likely slab, $42, is $50 short of the $92 all-in cost)
Raw value today$2 (from 50 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, 171 PSA-graded): 10 · 34%, 9 · 33%, 8 · 11%, 7 or lower · 22%. People send their best copies, so a random raw copy usually grades a bit lower.
Values when it comes back (~95 days, about Feb 13, 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.
