🗑️ The Garbologist says…
Too Thin To Call
The Garbologist sniffed around the sales pile.
- Only 1 recorded sale on the books — not enough for a trend without kidding ourselves. The last one changed hands at $24 on 2021-05-04.
- With this little to go on, the honest answer is we can't call a direction — one auction would swing the whole read.

🧬 Should I slab it?
Keep it rawAbout 1 in 2 copies of 2020 Sapphire Edition cards get a 10, and a 9 is worth $24 — less than the $92 it costs to grade. Even a 10 ($54) would leave you about -$38 after costs, not more than raw.
Expected value if gradedunder $0 (the likely slab, $36, is $56 short of the $92 all-in cost)

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 (2020 Sapphire Edition cards, 2,547 PSA-graded): 10 · 43%, 9 · 42%, 8 · 12%, 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 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.
