All collectors should have a good magnifier. They help save the strain of viewing tiny details and are invaluable when grading coins, checking for mint errors, varieties and detecting counterfeits. It is amazing how much more detail can be seen with a good lens. Exactly what type of lens to use depends on personal preferences. The more power you have the more details can be seen. However, higher powers generally provide a smaller field of view. Many collector s prefer the Anco 16X Jewelers Loupe. It provides a high degree of magnification with minimal distortion, and it fits in your pocket.
