Here's the deal.
I usually buy every tubular wheelset on the local CL with any Campy, Mavic, or DA bits.
That's why I am really stockpiling various Campy hubs, Mavic rims (various), and DA hubs. I also have a sweet tooth for Araya Aero 1's and and certain Wolbers.
I usually pay $50 to $100 per wheelset. After looking at Campy hub prices on ebay, I think it will be money in the bank.
As for yours, fifty to seventy five dollars would be the goin' rate here, although I am sure someone would slap a $250 sticker on them.
Nice wheels.
Set them aside until someone is begging for them.
