Features & Capabilities

Pingcoin is a cutting-edge Chrome extension that digitally replicates the classical "ping test" used to detect counterfeit gold and silver coins. By recording and analyzing the unique sound frequencies produced when a coin is tapped, Pingcoin accurately determines whether a coin is genuine or fake. This app supports a wide variety of popular gold and silver coins including Krugerrand, American Eagle, Canadian Maple Leaf, and many others.

The process involves pinching the coin at the center and flicking it softly to capture its resonance sound. The app compares these sounds against reference values with tolerance thresholds to give an authenticity indication. Pingcoin is designed as a complementary tool to visual inspection, weight, and diameter measurements, enhancing confidence when purchasing coins at fairs, garage sales, or from doubtful sellers. Users can also submit new coins within the app to expand the supported database. Overall, Pingcoin is an essential utility for coin collectors and buyers seeking a reliable digital method to avoid counterfeit coins.

User Reviews

Pingcoin is praised for its accuracy in detecting genuine silver and gold coins and its clean, simple user interface. It successfully identifies common coins but suffers due to a small database and a problematic user submission feature that limits new coin additions. Some users report issues with the app's listening duration and sensitivity during tests, causing it to stop prematurely or miss frequency readings. Occasional crashes and instability are also noted. Overall, the app is useful and functional but needs improvements in database expansion, submission reliability, and stability.

Pros

Accurate for detecting genuine silver and gold coins, useful for distinguishing fakes.
Clean, simple, and user-friendly UI that is easy to navigate.
Works well with common coins like silver Eagles, Morgans, and half dollars.
No bloatware, free and open source, appealing to users who want a lightweight app.
The ping test method provides a practical alternative for coin verification.

Cons

Small and incomplete coin database limits usability and accuracy for less common coins.
User submission feature for adding new coins is either non-functional or prone to errors, hindering database growth.
Issues with app listening time and sensitivity cause it to stop listening too quickly or fail to register some frequencies.
Some crashes and app instability experienced by users, especially on startup or during selection.
Lack of a robust troubleshooting guide or explanation for why some coins aren’t recognized or have unusual results.

Recent reviews

Seems to have been nice and accurate so far. I submitted two different gold Britannias, but so far they haven't been included. I'd be happy to give 5 stars if the dev would include them or explain why they haven't.

Nice app, can take a few tries (watch "How Pingcoin Works" in the app) to hit the coin & produce a sufficient ring, especially small & silver coins. Surprised there isn't a larger Db of coins (needs a search), IDK if that's bc dev isn't adding user submissions or users not submitting enough variety. The submission needs a description field to describe the kind of coin (I submitted 1/4oz AGEs but not sure if this was clear) & ability 2give a front & back pic.
