Rock Identification

[mu50stang]

This is my first year prospecting and it was lots of fun. I decided to pan my bigger gravels to get rid of them and everytime I got towards the bottom I found a few of these mettalic looking rocks. They would be at the bottom where the gold would be or close to it. They seem to reflect light real good and I can't figure out what they are. Also the big rock in my hand I had pulled of the front of my dredge and wasnt to sure what it was. It almost looks like it has a clear coat on it. None of them respond to my garret pinpointer(not sure if they are to small for this). Not sure if its worth keeping.

Appears to be pyrite in the pan
The big one reminds me of glassy leaverite
