silver ore

I would appreciate the help identifying it thanks!!! And as always keep hunting!

I found it on the rail road tracks where generally there is tons of regular iron ore. And while I was walking home from work, I found this small heavy rock, hammered it open, and I looked and saw silver possibly??? Any comments will be appreciated thanks!
