Coin Ping Test Holder

This holder is specifically designed for conducting the ping test on gold and silver coins. The test involves lightly striking the coin with a wooden or plastic object, producing a sound that helps identify whether the coin is genuine or counterfeit. Precious metals like gold and silver emit a long, clear tone, whereas base metals produce a duller, shorter sound. The design ensures the coin is securely held without direct contact to prevent damage, and is optimized for 3D printing.
