In General, (1) get optics with apochromatic lens. This is also called a triplet. It corrects distortion well and that includes color. With a lesser lens, you will think you have a lot of doubling and 'errors" when there really aren't any. (2) get the largest diameter lens you can afford. Note that expense increases with size, but you can see more area at the same time. The diameters of any maker of lens decrease as the magnification increases, so for most varieties and errors that make CRH sensible can be seen @ 10 to 15X, if you want higher and can afford it, go a binocular scope, which once you use it instead of a loupe, you will not regret it. I can search 5 coins with a scope than a magnifier with one. (3) use lights balanced so shadows or glare areas do not look like something. 2 on each side of coin at least. If you get a binocular scope, you can get a ring light , which covers the coin 360 degrees. If photography is a must, then make the scope triocular with a camera that record anything you see.
My recommendation is a belomo:
or if higher,
