Magnifying Glasses

Numismatic magnifying glasses are essential optical instruments for the careful examination of coins, medals and banknotes. They allow precise observation of striking details, reliefs, legends, mint marks and the state of preservation of a coin.

These tools come in several types adapted to the specific needs of collectors and experts: hand magnifiers, stand magnifiers, binocular magnifiers and LED-integrated magnifiers for optimal lighting when examining surfaces. Magnifications generally range from 5x to 30x, depending on the level of detail required.

The choice of a magnifying glass is based on several technical criteria: the magnification, the optical quality of the lenses (optical glass or achromatic lenses), the lens diameter influencing the field of view, as well as the ergonomics of the tool for prolonged use. Models equipped with achromatic lenses offer correction of chromatic aberrations, guaranteeing a sharp image without colour distortion, particularly useful for assessing states of preservation according to the Sheldon or Fleur de Coin scales.

The use of a quality magnifying glass is recommended for identifying die varieties, detecting overstrikes, analysing handling marks and examining surface details such as mint lustre, field texture or possible cleaning. These elements are decisive for evaluating the value of a coin in a collection or during transactions.

For professionals and experienced numismatists, high-magnification magnifying glasses equipped with an annular LED light are a preferred choice, combining uniform brightness and sufficient enlargement power for examining small modules or very fine striking details, particularly on ancient coins, medieval coins or high-quality modern coins.
