On the Vampire website, their interconnects are very inexpensive. The speaker wire isn't even sold anymore. They're probably not worth much at all to anyone, so she might just keep them and use them. If she sold them on Audiogon, the time she spent to box them up and paid to ship them, she'd probably be in the hole.
I have the same situation with an old Nakamichi interconnect that's Oxygen Free Copper. I actually use it on the TV to my Zvox sound bar, and in my stereo if I need an unbalanced interconnect. It's way too good to just give away.
