This is the best pocket glass we have found for coins and medals, it is the no.1 in its class in the US and we have used it ourselves daily for 5 years now.
The PO-55, MiniBrite™ pocket magnifier is a compact, 5x power, slide-out magnifier with a protective plastic sleeve. The PO-55 comes equipped with a built-in bright LED light. The sharp, distortion-free view is thanks to its crystal-clear acrylic aspheric lens. Aspheric lenses provide a clear image with no blurring and little to no distortion. The MiniBrite™ is a handy tool for those with low vision and is excellent for reading everyday items. The MiniBrite™ pocket magnifier is compact enough to fit in your shirt pocket or purse.
