Geology/silver colored heavy rock


silver layered rock
silver layered rock  
Can you identify this rock? It is layered, silver colored and somewhat iridescent. (glows purplish is certain light) It is very heavy. A little girl gave it to me 30 years ago. She said her dad found it in a field. I don't know any more about it. I live in southern Ohio where the rock was found.

Dear Sir
It is rock with mineral content-however it is difficult for me to come to conclusion
Local geologist will examine and will name the rick-kindly consult
