Creator of Pocket-Size Magnetic Imaging Device Launches Kickstarter Campaign

Esker W. Coffey, Inventor and Engineer, has launched a Kickstarter campaign to raise funds for the production of his pocket-size magnetic imaging device that allows users to see inside of objects such as gold coins and determine their metal content.

Esker W. Coffey, a noted Inventor and Engineer, has developed a pocket-size magnetic imaging device that allows users to see inside of objects in a manner similar to x-rays. These devices does not need batteries and will fit in the pocket.  Now, the inventor has launched a Kickstarter campaign to raise production funds to create this device and distribute it to a wide market.

The Internal Coin Scanner or ICS uses metallurgic technology to detect tungsten hidden inside gold coins.  Many fraudulent coin dealers sell coins as pure gold when, in fact, they have tungsten centers.  Because tungsten has a similar density to gold, it is difficult to tell by heft or even by water displacement if the central metal is pure or not.  The ICS allows users to quickly tell if the coin in question has a tungsten center.

According to Coffey, “Every metal has a unique magnetic susceptibility profile.  These profiles can be categorized into a magnetic ordering characteristic such as ferromagnetic, paramagnetic and diamagnetic.  Gold Lock’s Internal Coin Scanner or ICS capitalizes on this phenomenon to detect tungsten in precious gold.”  Users simply insert the coin into the device and watch for tell-tale color changes which indicate the presence of a base metal.

As seen at, the Kickstarter campaign offers pledge levels from $1 to $200, with rewards including Final Internal Coin Scanners with Shims and Prototype Coin Scanners.
