Monster Z 2 or 3 Series speaker cables

I bought a set of high end speakers from an elderly audiophile yesterday and he threw in these strange looking, huge, cables with banana plugs. I got home and started researching these things and I could not believe what some of them sell for, or what some people try to get for them. Theres a set exactly like mine for 800 on one site, 600 on another. They honestly cant be worth that, could they?  I read they were discontinued in 2006 and are hard to find. I honestly don't know a think about them

If they sell for that much, I'd flip them on Ebay myself !
