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 authentic or 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 rapidely with another hard object. Hold still the coin while it rings. When the sound of coin has diminished, knock it again.

Works great but the monthly subscription

I use it with the pocket pinger and works fantastic. But paying a monthly subscription for something you use a few times a month and maybe none the next. I understand you need to make money but I think you would make more if you had a low volume user fee. A one time $9.99 fee for low volume users. I am sure you would make a lot more money a lot of us are tired of subscription apps. it really starts to add up. Do you even read the comments I see no replies. Some money is better than none. Would be 5 star without subscription.

Has been accurate for me so far

I have tested 1 gold & several silver coins and also US 90% coins and it seems to be very accurate. Need to look up many of the coin weights for size, weight & purity myself since the database is mostly just US coins, but can’t complain since it’s free!
