Precious Coin Tester

Is that gold or silver coin real? Tap it, let it ring, and Precious Coin Tester tells you.

A fake can be made to the right weight and size. Getting the sound right is much harder: how a coin rings depends on its metal, right through to its core. Precious Coin Tester knows how each genuine coin should sound at its exact weight and size, and compares your coin's ring with it. That's how the ping test catches what a surface check misses, such as plated fakes and tungsten cores. Judging a ping by ear takes years of practice. The app listens for you.

WHY COLLECTORS AND STACKERS USE IT

• 43,000+ gold and silver coins: search by name, nickname or face value

• 650+ coins free to test, no subscription needed

• Minimum purity estimate for most coins

• Each coin's metal value at current gold and silver prices

• Custom coins: enter weight, diameter and fineness for anything not in the database

• Favourites saved to your account and synced across your devices

• No acid, no chemicals, no scratch plate, no extra kit

HOW IT WORKS

1. Pick the exact coin you're holding. The app can't see your coin: it compares the sound with the coin you pick.

2. Balance it on a fingertip near your phone's microphone and tap it with a hard object.

3. Hold still while it rings. Wait for the sound to fade before tapping again.
