摘要:
An apparatus and method facilitating a coin ping test that involves placing a coin in between two prongs that are covered with caps made of silicone, fabric, soft plastic, and/or other material or combination of materials that pinch and grip the coin tightly in place for a ping test. The elasticity of the caps also allows for the coin to be pressed down on one edge and then released, resulting in the coin snapping back down onto a hammer or surface causing the coin to ping on contact.
