Pingcoin is the digital version of the classical "ping test" for catching counterfeit coins. By recording and analyzing the sound produced by your coins the app is able to tell you if the coin is genuine or fake.
If you've ever found yourself not quite 100% sure about a coin's authenticity, try the ping test with the Ping Coin app. It will prevent you from getting fooled by counterfeit coins and it you will have peace of mind purchasing from even the shadiest coin sellers at fairs and garage sales.
How it works
A coin, like a musical instrument, produces a characteristic sound. Like a musical instrument this sound depends on its shape and on the material it's made out of. A wooden flute sounds different compared to a copper one. Similarly two coins of the same size and weight will sound differently based on the material they're made of.
The app will compare the characteristic sound of your coin (usually comprised of three frequencies) to my reference values. For each coin and for each frequency a tolerance threshold is displayed. If your coin's frequencies fall within the thresholds, it will almost certainly be genuine!
Important notes:
- The ping test works best as a complementary test to other tests. Do not rely solely on the ping test. Instead, combine it with a visual inspection and (ideally) weight and diameter measurements.
- Some coins of different composition, due to the variability in the coins' minting process and their natural wear, have practically indistinguishable sounds. A gold 1 oz Kangaroo and a silver 1 oz Kookaburra, for instance, will have practically indistinguishable resonance frequencies. Please note that this means that a test intended for one coin will work on the other and vice versa. This is why you cannot rely solely on the ping test.

How to ping your coin
https://youtu.be/b4LbRGKTNiE
Pinch the coin at its center keeping the surface area of your fingers to a minimum. (Imagine that the coin vibrates at the sides but stays fixed at its center.) Then flick the coin with a finger from your other hand. This can be done very softly. Don't worry if the sound is shorted and muffled, your smartphone mic will pick it up anyway.
