What is GOLD GAuGE?

Gold gauge is a device for non-destructively authenticating coins.

Why use GOLD GAuGE?

Gold coins can be faked.

Density measurements can be fooled.

X-ray fluorescence and acid only test the surface.

GOLD GAuGE offers a novel approach to authentication that is fast, accurate, and best of all, inexpensive.

How does GOLD GAuGE work?

Every object has modes of natural frequency dictated by its composition and shape. Even the slightest change to these parameters can have a profound impact on its acoustic spectra.

GOLD GAuGE measures multiple modes of natural frequency to confirm a coin's authenticity.

There is no spinning, dropping, or hammering the coin required. GOLD GAuGE uses a novel approach for measuring resonance without mechanical input from the user. Thus, GOLD GAuGE'S results are consistent and reproducible under all conditions.
