Straight from the Garbologist's clipboard:
  • 81 recorded sales · 14 in the last year · trades about once a month · high-confidence sample.

  • Median moved +20% across the window ($1,274 → $1,675).
  • Census check: PSA has graded 2,076 of this card, and only 1.6% come back a 10 — a genuine condition rarity.
  • 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?

Grade it

Fewer than 1 in 50 copies of this card get a 10; across every grade, a graded copy should be worth about $649, more than the $128 it costs to grade plus the $89 raw copy you give up.

Expected value if graded$521 (after $128 all-in cost)
Raw value today$89 (from 309 raw sales)
VerdictGrade it

Grading pays even without a 10.

How these numbers work
All-in cost $128: PSA Standard tier fee $60 per card (expected $86 with PSA's upcharge if it comes back worth more than the tier allows), insured shipping to PSA ~$12, PSA insured return shipping ~$30. Sending it to your PSA Vault instead skips return shipping (vault intake and storage are free): ~$98 all-in, so a graded copy would net ~$551.
Grade odds (this card, 2,076 PSA-graded): 10 · 2%, 9 · 13%, 8 · 23%, 7 or lower · 63%. 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.
