Silver 1 oz Chinese Lunar Year specifications and ping frequencies
The Silver 1 oz Chinese Lunar Year is a silver coin from the United Kingdom (2014–Present), weighing 31.1 g with a diameter of 38.61 mm. Tapped gently on its edge, a genuine one rings at about 4.5 kHz, 10.4 kHz and 18.0 kHz: its first resonance frequencies, set by its metal, size and thickness. A counterfeit made of a different metal, or with a different weight or thickness, rings at different frequencies, which is what the ping test above checks.
