🗑️ The Garbologist says…
Too Thin To Call
The Garbologist has been digging through this one's trash.
- Only 2 recorded sales on the books — not enough for a trend without kidding ourselves. The last one changed hands at $41 on 2026-06-20.
- 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.
