⤵ Sell · next 3 monthsIts one sale in the last 3 months, $450, was far above the about $125 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 has been digging through this one's trash.
  • 4 recorded sales · 2 in the last year · trades only a few times a year · limited-confidence sample.
  • The recent trail reads $123 → $100 → $125 → $450 — choppy but broadly rangebound.
  • Heads up: the last recorded sale ($450 on 2026-10-20) landed 22% above our current value — weigh it as a single data point.
  • None

🧬 Should I slab it?

Grade it

Raw value today$57 (from 19 raw sales)

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 ~$158.
Grade odds (2023 MLB Series 3 cards, 2,471 PSA-graded): 10 · 46%, 9 · 34%, 8 · 12%, 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 +5% (half the set's 3-month rise of 11%, 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.
