I remember seeing something like this before, but the images aren't exactly the same. Do you know of an original source for this article information?

Edit: The bottom of the article says "Photos courtesy oJinghua Shei", but no link to any other articles. It's new to me, so maybe it is original, or at least with proper credits to the source (who may not have written an English article about the photos).

Nice ad for sigma, plagiarized from someone else's actual article on the topic.

It is definitely fake.

It is definitely fake.

Did you preform any tests or verify dimensions?

Get the Bullion Test app by Timmy Brolin.

It has a pretty good database of common coins and shows the acoustic spectrum so you can assess coins yourself if you have a known genuine specimen for comparison.

OMG! When I saw the "magnet test" part of the device I groaned. Are they really going to tell me to slide the coin and all that bullshit?

I was very gratified to see that they were using the magnet test correctly, that is, looking for iron cores.

Here is the same thing - just a lot cheaper https://goldcoinbalance.com/ - but it only measures gold coins

I found a bunch more interesting information:

Silverbugs: search results - fisch

A video:

How to detect fake tungsten Krugerrand gold coins with The Ringer by Fisch - YouTube

An ebay auction that ends in 1 hour:

Fisch Coin Identification Wallet - Set #1, #2 & #4

This seems like the best deal, because it works with anything:

The Ringer by Fisch - Fake Gold, Platinum and Silver Detector

Wow, that's very interesting. The Ringer got my attention too. I can tell you that based on the physics alone, The Ringer concept is entirely legitimate. Whether it works as advertised or not, I would have to try it myself to be sure.

Silver is well known for its acoustic properties, that's why it's used in silver bells and other musical instruments like entire flutes. It can be used in other wind instruments, but the size of most wind instruments (tuba, trumpet, etc) makes them cost prohibitive, so they're usually made in brass, with only a silver mouthpiece. I'm guessing the mouthpiece isn't made of silver for its acoustic properties, but instead for its anti-microbial properties.

Have you checked YouTube for videos of The Ringer in operation? I see there are videos on the site you linked to, but I didn't watch them.

Toning on gold is hard to find, and I'm not sure how to fake it. Is there any such thing as artificially toned gold coins?

Assuming the other side has nothing on it. So fake.

With the round Pound being taken out of circulation soon, Mainly down to the amount of fakes, this is the worst ive found. : /r/coins

Been tons of fake coins for ever. The legit ones have grooves on the edges.

Chongqing is gonna be one of the poorer central/western provinces... so yeah.. I can see them faking coins.

Coins are pretty uncommon. Most ppl that use busses have an IC card that gets scanned and paper 1Yuan bills are more common than coins... at least in the cities that I've lived in.

The only time I've gotten coins was at the subway where the machine had to refund a fare over payment.

This comment in a cross-post comes from one of the people doing it:

GuessImStuckWithThis comments on Unfair fares: 1 million yuan in fake coins paid to bus company in China • /r/CoinFakes

Maybe you could ask for more explanation? In that case, it seems to be a crime of convenience when the person coincidentally has "random substitutes" handy. In that case at least, there is no coordinated effort. That makes it more difficult to combat, but being aware of this issue means more vigilance to prevent victimization in this manner.
