Coin Tester

By: Independent Trader

Gold and silver coins authenticity testing using AI and acoustic resonance.

Features & Capabilities

Coin Tester is an innovative Chrome extension that uses AI and acoustic resonance technology to authenticate one-ounce gold and silver coins. By analyzing the unique sound vibrations when a coin is struck, it distinguishes genuine coins from counterfeits, accounting for variations in minting year, wear, and patina.

Supporting popular gold coins like the American Eagle and Krugerrand, as well as silver coins like the Britannia and Noah's Ark, Coin Tester provides users with an easy-to-use verification tool. Subscriptions offer access for varying durations, ensuring updated coin databases and accurate testing across different vintages and conditions.
