Choosing a coin collecting loupe means picking magnification your eye can hold without distortion—10× is the sweet spot for legends and rims; 20× when you hunt star varieties or hairlines.
A pocket numismatic loupe should be light, centered glass, and cased so keys do not scratch the lens.
10× vs 20× in practice
- 10×: in-hand buys, shows, fast sort.
- 20×: desk work, varieties, photo documentation.
- >30×: eye fatigue—reserve for USB microscope.
Distortion and field of view
Rotate the coin on a fixed stand; hand-holding both pieces adds nausea. Raking light helps.
