🗑️ 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 $28 on 2024-10-12.
  • 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 5 in 10 copies of 2023 Intergoolactic Mayhem cards get a 10, and a 9 is worth $19 — less than the $92 it costs to grade. Even a 10 ($40) would leave you about -$52 after costs, not more than raw.

Expected value if gradedunder $0 (the likely slab, $29, is $63 short of the $92 all-in cost)
Raw value today$2 (from 3 raw sales)
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 2023 Intergoolactic Mayhem cards, 1,042 PSA-graded): 10 · 52%, 9 · 32%, 8 · 11%, 7 or lower · 5%. 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.
