🗑️ The Garbologist says…
Too Few Recent Sales
The Garbologist has been digging through this one's trash.
- 3 recorded sales · 2 in the last year · trades only a few times a year · limited-confidence sample.
- Following the trash: $200 → $102 → $380 — choppy but broadly rangebound.
- Heads up: the last recorded sale ($380 on 2026-09-15) landed 40% above our current value — weigh it as a single data point.

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 ~$211.
Grade odds (2024 Bowman Chrome Mega Box Bowman GPK cards, 620 PSA-graded): 10 · 47%, 9 · 37%, 8 · 12%, 7 or lower · 3%. 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.
