What type of wire is this and how to scrap?

My first question is what is this called and what type of metal would it go as if scrapped as is? Would it be better to strip out the copper wires? If so should I only strip the copper wireing down to the encasing or strip it down to straight copper? Any info and help is appreciated. I have been reading on this for a few days so I have done some research but I want to ensure I'm optimizing my return. I tried to upload and link a pic and neither will let me since i'm new i belive so if someone wants it in a message to post for me that would be great!

If you have that much of it, sell it by the foot to electricians. I would think 50-100 pounds of it, you have 50 to 100 feet at least. I am not quite sure the going rate, but I bet an electrician would jump at the chance to pick up BX 12? 14? with a ground at $2-3 a foot. It would also be very useful wiring a shed or shop. That is exactly the wire you would need to pull through wall unshielded (the flex cover is the shielding required). I would not scrap that wire, I would list it on CL or ask a buddy if they needed it.
