🗑️ The Garbologist says…
Too Thin To Call
The Garbologist has been digging through this one's trash.
- Only 2 recorded sales on the books — not enough for a trend without kidding ourselves. The last one changed hands at $1,450 on 2026-09-02.
- With this little to go on, the honest answer is we can't call a direction — one auction would swing the whole read.
Automated analysis generated from this card’s real recorded sales and PSA population data — no opinions, no predictions guaranteed. Entertainment and research only, not financial advice.

How these numbers work
All-in cost $109: PSA Standard tier fee $60 per card (expected $67 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): ~$79 all-in, so a graded copy would net ~$698.
Grade odds (all 2023 MLB Series 3 cards, 4,495 PSA-graded): 10 · 36%, 9 · 43%, 8 · 15%, 7 or lower · 6%. 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.
