🗑️ The Garbologist says…

Trending Up
The Garbologist popped the lid on this card.
  • 6 recorded sales · 3 in the last year · trades only a few times a year · moderate-confidence sample.
  • Following the trash: $36 → $34 → $21 → $49 → $42 — a clear march higher.
  • Median moved +18% across the window ($36 → $42).
  • Census check: PSA has graded 22 of this card, and only 50.0% come back a 10 — gems fairly readily.
  • Net-net, the momentum points up — real buyers are paying more, more often. Not a promise, just what the garbage is telling us.

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 3 copies of 1988 Original Series 15 cards get a 10, and a 9 is worth $18 — less than the $92 it costs to grade. Even a 10 ($49) would leave you about -$43 after costs, not more than raw.

Expected value if gradedunder $0 (the likely slab, $28, is $64 short of the $92 all-in cost)
Raw value today$3 (from 11 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 (1988 Original Series 15 cards, 2,223 PSA-graded): 10 · 35%, 9 · 41%, 8 · 12%, 7 or lower · 11%. 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.
