Copper - Pipe Amygdules
I have never seen a copper quite like this in person, though they are referenced in pre-1970s finds here (see ROCKS & MINERALS vol 81 #4, page 266 for example). These copper crystals somehow extended during growth to fill spaces in amygdaloid deposits, and form these strange "pipes".
