Thanks for throwing that out there. It's soft but not really that pliable. It will break off smaller chucks but not like pyrite or something with a greater hardness score. It sort of bends before if breaks if you know what I mean. None of the samples have that shield like structure of molybdenite. But thank you for giving me an alternative.

The latest photo looks more like Molybdenite to me.
In the text: Murdoch, J., Webb, R.W. (1966) Minerals of California Bulletin Centennial Volume (1866-1966) Bulletin 189, it is mentioned that, in part, for Eldorado County (where Placerville is): Broad foliated plates of molybdenite occur in a pegmatite with axinite and copper sulphides at the old Cosumnes mine near Fairplay, , Plates of molybdenite are found at Grizzly Flat, Trask reported molybdenite from the Pacific mine at Placerville.
Cheers

This being said, Molybdenite is indeed a good candidate for a shiny lead-grey mineral with foil-like look and structure and strong greasy feel in the hand.

(BTW, another vote for molybdenite.)
