Description

Worried your gold or silver coin might be fake? Counterfeit coins fool even experienced dealers — but they can't fake the sound.

Pingcoin uses acoustic analysis to verify coins in seconds. Just tap your coin, record the ring, and get an instant verdict.

✓ Results in seconds — faster than any other test
✓ See exactly why a coin passes or fails
✓ 37 coins supported, more added regularly

HOW THE PING TEST WORKS

Genuine coins produce characteristic resonance frequencies based on their metal composition, size, density, and stiffness. Gold rings differently than tungsten. Silver rings differently than copper-nickel. Pingcoin analyzes these frequencies and compares them against verified reference values.

If the frequencies match — your coin is almost certainly genuine. If they don't — you may have a fake.

TRANSPARENT RESULTS

Unlike other apps, Pingcoin shows you the resonance tolerance for each coin. You see your coin's measured frequencies, the expected range, and exactly how close the match is. No black box — just clear, visual verification you can trust.

SUPPORTED COINS

Gold (14): Krugerrand, American Eagle, Canadian Maple Leaf, Britannia, Kangaroo, Chinese Panda, Austrian Corona, and more

Silver (23): American Eagle, Morgan Dollar, Peace Dollar, Maple Leaf, Britannia, Kookaburra, Philharmonic, Mexican Libertad, and more

WHY TRUST THE PING TEST?

The ping test has been used by coin dealers for over a century. Pingcoin brings scientific precision to this traditional method using FFT frequency analysis — the same technology used in music apps and audio engineering.

Pro tip: Combine the ping test with weight and visual inspection for maximum confidence.

Comments on Pingcoin - Coin Ping Test for Android

★★★★★ G T · Apr 17, 2025

Ping testing works great. Only complaint would be that I can't submit a coin because it can't detect that my phone has a camera. Android 14 and Ping coin 0.1.41.

★★★★★ James O'Connor · Aug 29, 2023

Great app, much needed. I've used this successfully on silver Eagles, Morgan's and half dollars, but all the pre-65 quarters that I check only return the first 2 frequencies in range. Are quarters, being smaller, just not as easy to verify with a ping test? I'd assume dimes are even worse. Thanks!

★★★★★ rodger woggermon · Jul 22, 2023

Very good app for checking coins help me find 2 bad morgan silver dollar

★★★★☆ DanielB · Sep 8, 2025

I like it, but they haven't updated it with more coins since I installed it about 2 months ago. There's a lot of coins I have that aren't in this such as 25.00 half Gold Eagles for one not to mention the 1/10 Eagles. I have silver eagles and only 1 tested as fake. I have 2 counterfeit silver eagles that I bought purposely to test the Ping test apps and this app never gave them a total pass, but they did get 2 of the frequencies fairly often. Must have tested the fake coins at least 50 times LOL

★★★★★ John Doe · Sep 22, 2024

I don't believe the silver quarter one works. Other than those Everything else worked great. Thanks, saved me from fakes a couple of times, via the silver rounds test.

★☆☆☆☆ Adam Snyder · Nov 15, 2025

Used to be free and accurate. Now, can't authenticate any legitimate coin, forcing you to pay to upgrade for accurate results. Used to rely on it, now just terrible AND they want you to pay for it Edit: nice canned response, developer. doesn't change the fact that the app won't accurately detect unless you pay (which is actually zero free pings), and it may be a small price to pay, but why should I pay it to you? Edit: except it isn't improving, and you're asking too much.

★☆☆☆☆ David Slater · Sep 5, 2024

Will rate it higher once the description matches the app, it says it does 1oz gold britannia coins but there not on the list, only the 1oz silver britannia.

★☆☆☆☆ Michael Rush · Oct 19, 2024

I can't get it to listen long enough. As soon as I hit "start test" it listens for a split second then stops, as though it heard a ping. But there is no way there was enough time to even ping. If it listened longer maybe I'd have time to ping a coin. As it is, it stops listening almost as soon as I tell it to start. At first, I thought it must be because I was in a loud room or something, maybe the AC or fan was interrupting it. But no, I turned all that off, it was absolutely quiet.

★★☆☆☆ William Barnett-Lewis · Nov 4, 2025

Adequate for what few coins are available in it however the lack of huge amounts of older silver coins being counterfeited in China limit its usefulness. I personally would need to be able to test UK sterling & 50 % silver Crown, Half Crown, Double Florin, Florin, Shillings, 6 pence & 3 pence before it would be worth upgrading the app. Canadian and European (French, German, Netherlands, etc.) silver coins as well.
