Answer 1

There are several silver coloured metallic minerals, but they don't usually have the textures seen in the example.  Galena is very heavy, silver coloured, but it comes as cubic crystals - galena will make a black mark if you scratch it on a rough piece of porcellain.. Specular haematite is silvery and flakey in texture, and it will make a reddish-brown mark on porcellain. If it is silver it will make a silvery white mark.

Answer 2

Silver is found naturally occurring as a metal, so I would not be surprised if you have a silver nugget. I cannot think of any naturally occuring mineral which would look like silver,i.e. fools silver.
