🗑️ The Garbologist says…
Too Thin To Call
The Garbologist has been digging through this one's trash.
- Only 1 recorded sale on the books — not enough for a trend without kidding ourselves. The last one changed hands at $744 on 2025-09-23.
- With this little to go on, the honest answer is we can't call a direction — one auction would swing the whole read.

How these numbers work
All-in cost $112: PSA Standard tier fee $60 per card (expected $70 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): ~$82 all-in, so a graded copy would net ~$808.
Grade odds (all 2024 Bowman Chrome Mega Box Bowman GPK cards, 979 PSA-graded): 10 · 49%, 9 · 36%, 8 · 11%, 7 or lower · 4%. People send their best copies, so a random raw copy usually grades a bit lower.
Values when it comes back (~95 days, about Jan 21, 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.
