Mystery silver-looking metal Help

[WatchCollector56]

This box of metal was recently found in an estate. It is not magnetic and doesn't test for silver. I was hoping if someone could tell me what it is? and if it has any value?
Thank you!

I can't tell what size they are, but they look like electrical contacts. But then again, I thought contact were made of silver.

Nickle electric contacts maybe. They were sometimes nickle plated copper or brass .
