Coin Tester Testing the authenticity of gold and silver coins using AI and sound.

Coin Tester is an advanced application that allows the user to check the authenticity of one-ounce gold and silver coins. The application uses the acoustic resonance method (the so-called ping test) and artificial intelligence to verify whether the user is dealing with a genuine currency.

When the coin is minted, it vibrates and emits a unique sound, the color of which is mainly influenced by the dimensions and material from which it is made. For example, a gold Maple Leaf will sound different than a silver Krugerrand when struck. A genuine gold or silver coin will sound different from a counterfeit. These differences are used by the Coin Testerrummy noble apk application.

An interesting fact is that every year the mints issue coins with a new physically minted year. Furthermore, changes in the coin production process, wear and tear or the appearance of patina on the silver are small differences that affect the sound of the coins.

Using artificial intelligence, the Coin Tester app guides the user through the coin verification process, helping to verify the authenticity of the product. We have access to a large database of new and circulating coins, thanks to which we regularly add updates covering new years coins, so that the user has the correct functioning of the application with all types of coins, regardless of their condition, type or year of minting.
