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.
