fair price for Aural Thrills Audio Silver intercon

I have three pairs of Aural Thrills Audio Silver cables with the teflon/copper connection, and I'm wondering what I should ask for them as a fair price?
Best regards,
what are they going for new in his ads on audiogon?
I searched, but found no adds, only auctions.
Thats why I posted the question, not sure what they're going for.
