The invention disclosed herein generally relates to a device and methods to authenticate the composition of materials, including, but not limited to gold and silver coins and gold and silver bars. The invention stimulates the natural frequencies of the tested object and then compares them to a reference dataset to confirm its authenticity. It achieves this through use of a transducer that both vibrates the object and collects amplitude response, allowing for consistent and highly accurate analysis across a broad spectrum, including ultrasonic frequencies.
