🗑️ 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 $16 on 2026-07-24.
  • 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.

🧬 Should I slab it?

Keep it raw

About 1 in 2 copies of 2021 Chrome cards get a 10, and a 9 is worth $28 — less than the $92 it costs to grade. Even a 10 ($100) would leave you about $8 after costs, not more than raw.

Expected value if gradedunder $0 (the likely slab, $60, is $32 short of the $92 all-in cost)
Raw value today$16 (from 1 raw sale)
VerdictKeep it raw

Even a PSA 10 would not beat the raw value.

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 ~under $0.
Grade odds (all 2021 Chrome cards, 3,613 PSA-graded): 10 · 45%, 9 · 46%, 8 · 7%, 7 or lower · 2%. 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 (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.
