Looks possibly like some sort of mica, though hard to tell from the picture. Perhaps post some better pictures, and test items such as hardness and streak, as well as provide locality info.

I will go and do the basic tests to them and post results, not that I read how too. Location I cannot provide because they are in a collection my gramps had, and there is no info where he got them

Ok. Aside from locality, most important properties generally are hardness and streak.
