The CoinTrust app

Check the authenticity of your gold and silver coins with a unique sound verification method (ping test / ring test).

Dating back as far as the ancient times experienced traders could distinguish between pure gold and fake coin listening only their sound. They did not need to bite coins, measure or pour acid, it was enough to listen the characteristic "ring" of the coin.

Today, this knowledge has been used in the CoinTrust application, available for your smartphone.

Start the app, choose your coin from the list and gently spin the coin on any table and the test result will show up on the screen.
