  • Following the trash: $20 → $20 → $55 → $42 → $75 — a clear march higher.
  • Median moved +178% across the window ($20 → $55).
  • 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

About 1 in 2 copies of 2023 MLB Series 3 cards get a 10; across every grade, a graded copy should be worth about $134, more than the $92 it costs to grade plus the $14 raw copy you give up.

Expected value if graded$42 (after $92 all-in cost)
Raw value today$14 (from 11 raw sales)
VerdictGrade it

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 ~$62.
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.
