Using a Coin Collecting Microscope

Whether you’re just starting out or are a seasoned numismatist, a coin collecting microscope can help you identify and inspect a wide variety of coins for flaws or other details. The right kind of microscope can also help you make more informed buying decisions and even spot errors crystal clear.

A common laboratory microscope uses two optical components to determine its degree of magnification: the objective, which magnifies the object, and the eyepiece that presents it to the user. While common lab scopes often offer choices of 5X or 10X objectives, these are typically too powerful for numismatic use.

You can also look for a digital microscope, which allows you to view the image of the coin on an LCD screen. This can save your eyes from fatigue and is useful for examining large numbers of coins at once. Some digital coin microscopes are designed for easy operation, so you can simply turn them on and start inspecting.

Using a coin collecting microscope can also help you spot traces of cleaning products or brush fibers, as well as other features that may be indicative of the coin’s age or origin. For example, if you see fine red fibers on the surface of an ancient bronze coin it might have spent time in a flocked tray. Scratches that follow a pattern can also help define authenticity.

The condition of a coin significantly impacts its value. A coin that’s in pristine condition with minimal wear, known as uncirculated, is more valuable than a heavily worn one.
