▼ Volatile: the raw price moved -30% in the last 30 days. PSA Standard takes about 90–100 business days (roughly 4–5 months), so this pick is more sensitive to the price moving before the slab comes back.
Pop reports count submitted cards, and people mostly submit their best copies, so the real odds for a random raw card are likely a bit lower.
