## What is Precious Coin Tester?

Test precious metal contents in gold coins and silver coins:
- Detected countless fakes and saved users thousands of dollars in 2024
- Over 600 free coins available now!
- Access 2000+ coins with high-precision results!
- Full-text search through a massive up-to-date database of over 40,000 coins!

When you get a silver or gold coin with correct weight and size, how can you know it is not a fake coin made of other cheap materials? Traditional ping tests can distinguish true gold or silver coins from counterfeit ones in cheap metal. But you need good ears! 

Precious coin tester helps you listen to the sound generated by the ping test and will tell you whether the coin is a cheap metal fake. So no more worry about the fake gold or silver coin!

How to ping the coin?
Hold the coin on the tip of one finger near the mic of your phone/tablet, and knock the coin briefly with another hard object. Hold still the coin while it rings. When the sound of coin has diminished, knock it again.

Which results are good?
Both 2 and 3 stars are good results:
- 2 star offers standard/traditional ping test result, it indicates that the sound of the coin matches that of a genuine one. It is a qualitative result.
- 3 star is our uniquely developed high precision result, it indicates metal content error is under 10% for silver and under 5% for gold.

Spot a 3-star false positive and you may win a $100 reward! Details: https://preciouscointester.com/en/3_star_quest/round2/3_star_quest.html

### 5/5 — Saving money

*2026-03-29, version 2.3.9*

Saved me so many times

### 5/5 — Thankful!!

*2026-03-06*

Finally an app that isn’t trying to bleed you for money! I appreciate this company for making this app easy to use and free of charge!

THANK YOU!!!

**Developer response:** Thanks for your review!

### 3/5 — Clunky

*2025-03-27*

This app does what it’s supposed to but using it needs improvement. The search feature is terrible. I ran a search for “0.25 eagle” and it returned zero results. Then tried again and it came back with only two results, both were for half ounce coins. Trying to find the most basic coins is a chore so after over a year of paying for this app, I’m leaving and will verify my gold and silver purchases through alternative means.

**Developer response:** Hello,

We are sorry to hear that. Would you like to try "Gold eagle" directly as keyword? The app has a huge database and the search sometimes cannot find the optimum results.
Please feel free to reach out to us by email, we are happy to help on any concerns on the app.

We will also work on reducing the difficulty in the coin search. 

Best regards,
Precious Coin Tester team

### 5/5 — Money saver

*2025-01-10*

Without this tool, I would have accepted over $1,000 in bogus Morgans and Silver Ridge coins. 
More than pays for itself on a daily basis.

**Developer response:** Thanks a lot for your review! We are very happy that the app has helped, it's our objective :)

### 1/5 — Network Error

*2024-12-08, version 2.1.1*

I’ve tried using the app multiple times with different coins and always got a “network error” message.

### 4/5 — Accurate but hard to use User interface

*2024-11-19*

The app seems to be working very accurately, however, the user interface is very finicky and could use some very basic upgrades, such as being able to save the most used coins. That way you don’t have to look for them every time, and improving the search function as it could be very difficult to find some coins

**Developer response:** Thanks a lot for your review! We understand your concerns. The search ability should have already been improved in 2.1.0. If you find any concrete examples of search issues, please drop us a mail at preciouscointester@gmail.com. We are more than happy to know them! We will also continue on improving other aspects to make the app easier to use :)

### 2/5 — Not useful

*2024-10-23*

Most the various coins are locked until you pay. I tried to test a few coins to try this app out and it doesn’t work. Clicked “check” then clinged my coin and nothing, tried again and again, doesn’t work. No waves no response nothing. My coins gonna get scratched up plus they keep falling onto the floor. Time for a new tester.

### 1/5 — New Point System is not good

*2024-10-12, version 2.0.9*

What is the new point system?  Why do I need points if I’m already a subscriber?

1 star for unecessary popups and no explanation

### 4/5 — Zzz

*2024-10-07*

Works pretty well. Sometimes see “network error” when trying to use, but usually it works.

**Developer response:** Hello, we are sorry for what you have experienced. Would you please drop us a mail at preciouscointester@gmail.com with more details, so we can investigate and solve the issue?

### 3/5 — Better than nothing

*2024-10-07*

Gave me a 3/3 rating for a glass jar while testing for ASEs. Just another data point, don’t bet the house on just this app. Update - the right coin was selected, the point is you can fool the app with false positives.

**Developer response:** Hello, the correct coin needs to be selected before performing the test in order to have a meaningful result. (Otherwise, you can use a musical instrument to get any result you want :D) You can find some best practices here: https://preciouscointester.com/en/best_practices.html
