  • Census check: PSA has graded 482 of this card, and only 7.1% come back a 10 — tough to gem.

🧬 Should I slab it?

Only if you're confident it's a 10

Only about 1 in 14 copies of this card get a 10. A 10 is worth $594, but after the $92 cost it barely beats the $13 raw copy.

Expected value if graded$15 (after $92 all-in cost)
Raw value today$13 (from 117 raw sales)
VerdictOnly if you're confident it's a 10

Break-even: you need about a 7% chance of a PSA 10 (this card: 7%).

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 ~$35.
Grade odds (this card, 482 PSA-graded): 10 · 7%, 9 · 32%, 8 · 32%, 7 or lower · 29%. 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.
