⤵ Sell · next 3 monthsIts one sale in the last 3 months, $15, was far above the about $10 it sold for in the nine months before. After a jump like this the next sales usually came in lower than the jump sale, though well above the old price (1,655 cards since 2019). The set is rising, but this card has already jumped well ahead of it.

🗑️ The Garbologist says…

Too Few Recent Sales
The Garbologist sniffed around the sales pile.
  • 5 recorded sales · 2 in the last year · trades only a few times a year · limited-confidence sample.
  • Following the trash: $8 → $8 → $21 → $10 → $15 — choppy but broadly rangebound.
  • Census check: PSA has graded 166 of this card, and only 33.1% come back a 10 — gems fairly readily.
  • None

🧬 Should I slab it?

Keep it raw

Only about 1 in 3 copies of this card get a 10, and a 9 is worth $27 — less than the $92 it costs to grade. Even a 10 ($87) would leave you about -$5 after costs, not more than raw.

Expected value if gradedunder $0 (the likely slab, $44, is $48 short of the $92 all-in cost)
Raw value today$2 (from 29 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, 166 PSA-graded): 10 · 33%, 9 · 41%, 8 · 12%, 7 or lower · 14%. 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.
