Place the eight guides on your slab photo, then analyze how centered the printed design sits within the visible card borders. Built for collectors who want a structured read—without guesswork.
Drop a clear, head-on photo of your card in the holder. For best results, avoid heavy glare and keep the full slab in frame.
On iPhone, choose a JPG/PNG photo. HEIC images may not load — switch Camera → Formats to “Most Compatible” if needed.
