Is the sound test a good counterfeit detection method?

The sound test is only suitable to a limited extent for a reliable authenticity check of precious metals. With experience you can detect forgeries, but with some alloys or certain manufacturing processes (e.g. sintered forgeries) the sound can be imitated very well. Therefore, this test is not recommended. 

We suggest other and safer methods and devices.
