AudioQuest Pegasus "fever" RCA cables

Aloha, does anyone remember or have a set of AudioQuest Pegasus "Fever" RCA cables? I listened to a pair and liked them. They look pretty old and are for sale locally, but the person has no idea of their value and I can't seem to find any reference to them on the web. Anyone have a sense of what they are worth on the used market?

Thanks....
