Precious Coin Tester

Discover the truth about your gold and silver coins with our Precious Coin Tester app:

🎉 Free Access to over 600 Coins - Start testing immediately!
🥇 High-precision for over 3,000 coins with semi-quantitative results.
🔍 Rich database containing over 40,000 coins.
🛠️ Custom Parameters - Customize testing parameters to suit any coin's unique attributes.

Not sure if your coin is genuine or a counterfeit? Our app simplifies authenticity checks. Unlike traditional methods that require a fine ear for sound, Precious Coin Tester analyzes the sound from a simple "ping" test and determines if your coin is made from precious metals or cheaper materials. No more uncertainties about your coin's authenticity!

How It Works:

1. Place your coin on the tip of your finger near your device’s microphone.
2. Tap the coin with a hard object and let it ring.
3. The app listens and analyzes the sound. Knock again when the ringing stops.

What Do the Results* Mean?
0-star: Negative result
1-star: Warning zone. You may need probably double check input parameters.
2-star: Your coin’s sound matches that of a genuine coin.
3-star: High-precision result: metal content error is under 10% for silver and under 5% for gold.

Differences between 2 Stars and 3 Stars?
2-star is a qualitative positive result. It is what traditional ping test offers.
3-star is our unique high precision result. It states clearly the metal content expectations.
🤑 Spot a 3-stars false positive and you may win a $100 reward! Details: https://preciouscointester.com/en/3_star_quest/round2/3_star_quest.html
