Place the coin on a clean white background, such as a sheet of white paper. This helps to distinguish the object and improve photo quality. For a clear image, hold the phone parallel to the surface of the coin.
Always photograph both sides of your coin for accurate identification. Natural daylight provides the best lighting conditions.
