[QUOTE="Collect89, post: 1380506, member: 15445"]Hello Tristen1230, This was an important question from Hobo. For grading I personally use a high quality 3x that allows convenient viewing of the entire coin under different lighting conditions. Higher magnifications can make it difficult to position the coin, your head, & the light. Higher magnifications can also make it impossible to view the entire coin at the same time unless all you collect are dimes. You should use the same high quality glass all the time for consistent grading. Once you assign the grade, you may want to look for varieties or attributions such as full bands etc. For this, I find a 10x loupe or 15x loupe works for me. The 7x does not give my poor eyes enough resolution to really see mint marks, varieties, and counterfeit diagnostics. Of course, these suggestions are for use in the field. If I'm at home I still use the same 3x for grading but I can use a binocular microscope to see the really little things.[/QUOTE]
