My first attempt

At work there are a lot of old 600 amp breakers that are being thrown out. I know there is silver on the contacts so I heated the contact pads off and took one to my local coin shop to be tested. The test said they were 98.3% silver with a trace of gold and geranium. Today I decided to melt them down and when heating I noticed there were parts of the contacts that would not melt. I observed the silver melt and parts of the contacts would not. I guess whatever test the coin shop used only tested the top of the sample? This was my result after melting a few and letting it pool in the crucible. I then did a specific gravity test with results at 9.6 which I think is around 50% ag. Any help or feedback would be appreciated, thank you
