Pingcoin: Gold & Silver Tester

Pingcoin: Sound-based counterfeit coin detection – Authenticate gold & silver coins in seconds with the ping test

Tired of counterfeit coins flooding the market? Pingcoin is the must-have mobile app that turns your smartphone into a professional-grade counterfeit detector. Using cutting-edge resonance frequency analysis, verify the authenticity of your gold and silver coins with just one tap – no damage, no hassle, no expensive gear required.

Why Pingcoin? Protect Your Investments Effortlessly

In a world where fake coins are flooding the market, Pingcoin empowers collectors, investors, and dealers to spot fakes instantly. Based on proven physics principles – like the traditional "ping test" but supercharged with modern, digital techniques – our app analyzes the resonance frequencies of a coin and compares it to known resonance profiles. Although counterfeiters might succeed in matching diameter, thickness and weight — this necessarily requires them to use materials that ring VERY differently. Pingcoin catches these counterfeits.

• Supports 36 Popular Coins: From American Eagles and Canadian Maple Leafs to Buffalos, Philharmonics, and Krugerrands – we've got 20 silver and 16 gold types covered.
• Non-Destructive & Lightning-Fast: Gently tap your coin, record the sound, and get an "Authentic" or "Not Recognized" verdict in milliseconds. No scratching, acids, or tools needed.
• Works Anywhere: Test at coin shows, estate sales, or on the go.
• Science You Can Trust: Powered by Finite Element Method (FEM) simulations and vibrational analysis, the same tech used in aerospace and bridge inspections for material verification.
• Work with (or without) physical pingers like the pocket pinger

Combine with weight, diameter and thickness checks for a comprehensive approach.

How It Works – Simple as 1-2-3

1. Select Your Coin: Pick from our library of 36 coins.
2. Tap to Record: Hold your phone close and give the coin a gentle ping.
3. Get Instant Results: Advanced algorithms compare frequencies to verified references – done!

How does it compare with other ping test apps?

• Transparency: Pingcoin shows you what is being measured. We show you each resonant frequency and the tolerance we're using to base our verdict on. Most apps don't do this.
• No hardware necessary: You can use Pingcoin with just your phone and your coin, but if you want to use a pinger, you can.
• Speed: Pingcoin analyzes the ping of your coin within a split second.
