Ping test for any gold coin silver coin: free tier (>100 coins) + subscription

When you get a silver or gold coin with correct weight and size, how can you know it is not a fake coin made of other cheap materials? Traditional ping tests can distinguish true gold or silver coins from counterfeit ones in cheap metal. But you need good ears!

Precious coin tester helps you listen to the sound generated by the ping test and will tell you whether the coin is a cheap metal fake*. So no more worry about the fake gold or silver coin!

You can choose your coin from a catalog including more than 30,000 coins**, where more than 100 of them are free. Nothing found in the catalog? Defining coin's parameters by your own is also another option**!

- How to ping the coin?

Hold the coin on the tip of one finger near the mic of your phone/tablet, and knock the coin briefly with another hard object. Hold still the coin while it rings. When the sound of coin has diminished, knock it again.
