Great Ball [Reverse Holo], FireRed & LeafGreen, +996.77%
This is exactly the kind of move that deserves skepticism first. FRLG reverse holos are genuinely tough and collector-loved, so I’m not dismissing the card, but a 10x weekly move usually means the market had almost no reliable transactions to begin with. Watch for follow-through sales. If they don’t show up, this spike will fade.
