At home density test - Specific Gravity
Dry weight / Submerged Weight = Specific Gravity
The home version of this test isn’t perfect, but it can catch many of the common metal fakes.
The ping on this one matches what I’ve learned to be Tin on a spectrum analyzer.
Maybe a test error or it’s actually a Tin/Zinc hybrid? Maybe what I learned was wrong?
For sure, not Silver.
Fun test to play with, and of course, always best to use multiple testing methods.

Any difference in sound is a strong indication that further testing is needed. Always use multiple testing methods.
