Best Practices for Online Scanning

• Use the highest resolution your camera supports
• Steady your phone against a surface to prevent blur
• Use natural daylight or a bright desk lamp
• Place the coin on a solid-color background (dark for light coins, light for dark coins)
• Avoid using flash directly — it creates harsh reflections on metal surfaces
