🗑️ The Garbologist says…

Too Thin To Call
Straight from the Garbologist's clipboard:
  • Nobody's actually sold this exact card and grade on record, so there's no live market to read — the price you see is a modeled estimate, not a realized sale.
  • 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 6 in 10 copies of 2020 35Th Anniversary cards get a 10, and a 9 is worth $67 — less than the $92 it costs to grade.

Expected value if graded$16 (after $92 all-in cost)
Raw value today$42 (typical of 4 older raw sales (newest Dec 2023)
VerdictKeep it raw

Break-even: you need about a 91% chance of a PSA 10 (all 2020 35Th Anniversary cards: 61%).

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 ~$36.
Grade odds (all 2020 35Th Anniversary cards, 1,660 PSA-graded): 10 · 61%, 9 · 24%, 8 · 9%, 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 13, 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.
