Check the authenticity of your gold and silver coins with a unique sound (ping / ring) verification method.

CoinTrust app allows you to verify the authenticity of your gold and silver coins. Simply spin your coin on a table and the app will tell you if your coin is a genuine one.

The app compares characteristic frequencies of your coin with the pattern of the original one.

This method is simple but effective and noninvasive. It is one of a few methods which can recognize debased coins and tungsten-filled coins (as soon as they appear on the market).

CoinTrust app offers free tests of the following coins:
• gold Krugerrand 1oz
• Canadian Silver Maple Leaf 1oz (2005-2013)

The following patterns are available for an In-App-Purchase ($0.99 each):
• gold Vienna Philharmonic 1oz
• Canadian Gold Maple Leaf 1oz (1979-1989)
• gold 10 Rouble (1897-1911)
• American Silver Eagle 1oz

We will provide patterns of gold and silver Maple Leaf, American Eagle, Philharmonic, Chinese Panda, Australian Kangaroo and other, soon. Release dates and prices of other patterns are available on our website.

The app works 100% offline and doesn't collect any data from your device.

Sprawdź autentyczność swoich złotych i srebrnych monet bulionowych za pomocą unikalnej metody dźwiękowej.

Aplikacja CoinTrust pozwala na zweryfikowanie autentyczności złotych i srebrnych monet, poprzez porównanie charakterystycznych częstotliwości rezonansowych testowanej monety ze oryginalnym wzorcem. Wystarczy zakręcić monetą na twardej powierzchni a aplikacja wskaże czy twoja moneta jest prawdziwa.

Ta metoda jest prosta, ale wyjątkowo skuteczna, tania i bezpieczna dla monet. Jest to jedna z niewielu metod, która pozwala rozpoznać monetę o zaniżonej próbie oraz wypełnioną wolframem (jeśli takie pojawią się na rynku).

CoinTrust pozwala przetestować następujące monety:
• złoty Krugerrand 1oz
• srebrny Maple Leaf 1oz (2005-2013)

Po uruchomieniu aplikacji można "wewnątrz" niej dokupić dodatkowe wzorce (€0,89 / wzorzec):
• złoty Filharmonik Wiedeński 1oz
• złoty Maple Leaf (kanadyjski Liść Klonowy) 1oz, roczniki 1979-1989
• złote 10 Rubli (1897-1911)
• American Silver Eagle 1oz (Amerykański Srebrny Orzeł)

Wkrótce dostępne będą kolejne wzorce, złoty i srebrny Maple Leaf, American Eagle, Wiener Philharmoniker, chińska Panda, australijski Kangaroo Nugget.

Aplikacja do pracy nie wymaga połączenia z internetem. Nie są też zbierane żadne dane.

Jakkolwiek VeriGold Sound Ltd zrobił wszystko, żeby uczynić aplikację CoinTrust tak dokładną i wiarygodną, jak to tylko możliwe, firma nie ręczy za dokładność wyników testów i jednoznacznie oświadcza, że nie ponosi żadnej odpowiedzialności za ewentualne błędy w procesie weryfikacji.

Customer Reviews

Great App

Love it. Been able to capitalize on deals I would normally feared to good to be true but with the app I really fee confident. VERY sensitive so be sure older coins have dirt etc. removed. The extra time this may take is well worth the knowledge that you are buying the real deal. Keep up the good work! Hope to see many expansions and I'd be willing to pay for probably all of them.

Awesome but Limited

The good news – extremely accurate. The bad news – Way to accurate.

The App worked wonderfully at picking out an American Silver Eagle coin amongst many other coins including other silver coins. It also did well at picking out Canadian Mapleleaf silver coins within a narrow band of years. Unfortunately, it's like owning a microscope that doesn't allow you to adjust the focus. ( btw I only tested the silver portion of the app )

This app would be so much more amazing if it allowed you to adjust the sensitivity to the sound of silver in general and come back with a probability meter.

I so want to give this app a five star rating! It's a wonderful idea and has great potential. I promise to come back after the next update with a reevaluation.

Kudos and best wishes to Cointrust!

A beautifully made useful and accurate app!

It does what it says, based on real science of specific sound frequencies.

I tried to trick this app and could not do it.

Interface is user friendly and very nicely designed.
